When I first bought it (02-27-2005):

Running on 3 cylinders, no air filter, blown out muffler, badly leaking power steering lines, and a CA20E. Probably 70BHP at the time (before the tune-up, of course).


Now, a few used/knock-off items from eBay:

What else...

Oh, this isn't really new, but this is all my dashboard is:

And, I went from this, which is actually the weather boot that's under the interior's boot, but it didn't last too long and the rubber tore:

Now I have it set up like this:

Looks really good man, and HOLY thats a short shifter. Doesn't it take quite a bit of force to shift it being that short?
Title: Matt's S12
Post by: seishuku on 07:47:08 PM / 03-Aug-07
Nah, actually it's pretty easy to shift. 1-4 is no problem, 5th is a little bit of a stretch, otherwise it's pretty comfortable.

Maybe my trans is just a little worn out with 140k+ miles on the clock, but I can still blast through the gears no problem!

Wow.  Ok wow.  Your ingenuity is blowing my away.  I love stuff like that.  You get a big big thumbs up from me.  This reminds me A LOT of my honda days.  CRX with a custom laid back radi out of a ford ranger, lol.  Anyway, great job on your car and I'm sure you've only just begun.

nice dood, i cant wait until i get my sr20de. it has like what 140 hp? or more? do u also know how much hp a stock s12 has?
Title: Matt's S12
Post by: seishuku on 08:09:11 PM / 22-Aug-07
140BHP for the S13 (9.0 or 9.5:1 compression, no VTC), and 160BHP for S14 (10:1 compression, and VTC).

The stock CA20E has about 100BHP, CA18ET is 125BHP, VG30E is 160BHP.

The power will be right along with the SE S12, only the SE will have a little more lower end torque (it's a V6, duh!  ).
Otherwise, the SR20DE has a pretty awesome powerband, I was pretty happy with my S14 DE. Even more now that it's turbocharged, same low end, but a ton more high end.

It looks like you haven't cut the trans tunnel back for the shifter so you are running your old ca20e transmission. Did you swap an sr gbox front cover onto it to match the engine??

Nice work by the way.

Are you going to trim up your guage surround to fit into your dash in place of the original instrument cluster?

Yup, I bought a bell housing that Import Intelligence had laying around, and just swapped it onto my original CA trans. Took about 4 or 5 hours to do, but once I got my trans apart, it was pretty simple.

very impressive work mate. I love the home style job, but also done with a do it once do it right attitude.

I'm sure ur stoked with it. i'd love to have a ride in it, but the flight over is too much

my mate has a CA18de+t in his sil and that thing pulls hard! I can only imagine that it would be better again.

Paint work looks like a decent job too.
Title: Matt's S12
Post by: seishuku on 06:37:51 PM / 11-Sep-07
Everyone that had rode in it has been pretty impressed, though they were mostly our local "ricer brigade" that I only really know two that hang out with the rest.  Mostly Honduh, Caviler, Neon, some gutless fox-bodies, and a ford probe.

The paint will get some more work done, probably will get some clear coat too... Now that we have a garage I can work in... Just need to run some power out to it.  Then I can get some more work done on the new rear suspension too.

Finally got the house all situated then huh? I wonder if we are closer or farther now... Should probably do a small Fall meet just to shoot the shit and drink beer.

Which reminds me, I should get some pics of the Bug and post them up. Hopefully I can get tires, brakes and some misc. other stuff to get it running by spring.

 I like

The reason for the wheelcovers, the car had them on when I sold it to him.  I bought the car from a guy who had brought it up from Arizona, and he had done some appearance-type things to it so it didn't look real bad.  Then it sat, and got kinda beat-up a bit, thats when I ended up with it....

Yup, moved in a few weeks ago, still haven't made our first payment yet though (next month).
Not much closer, I only moved across town, probably only 8 miles closer.

I'd defiantly be up for a fall meet somewhere, not a clue where though.
Someone might have to call me if anything is going on though, I'll probably be with out an internet connection for a little bit. Bastards at AT&T don't offer DSL at the new house.

Alright, still nothing much new, added a boost controller, upped it to around 8 or 9 PSI with maybe a 10PSI spike. Makes a HUGE difference from 7PSI, must have had too much fuel for 7PSI.
AFR's still peeked at 9:1 according to my datalogger, but I saw a steady 11.8:1 while holding full boost.
With the controller, it reaches full boost much faster as well, I have full boost by about 2800RPM, and that's on my tired and used T25.
The controller is just a bleeder type, made with a few hose barbs, a tee, and a needle valve for an Oxy torch.

I'm still researching for the suspension, still trying to get enough power out in the garage to run the welder. I only have a 50' extension cord, so I pretty much only have lights.
After looking at the wiring out there, I might have to rewire everything, and the welder needs a good circuit. I won't be finish welding it with, since it's only a 120volt portable, but it's more than enough to tack it together and take to work and finish it with a MIG or TIG (if I can get some time on the TIG, we only have one, unless I can slap one together).
Title: Matt's S12
Post by: 200sxkitcar on 12:51:58 PM / 07-Oct-07
I *might* be able to tig for you, I have a portable Lincoln Invertec 205 that runs on 120v-440v, auto-sensing, with all the gear.  Do you have a electrical panel near your garage?  Its not hard to run a 220V line
Title: Matt's S12
Post by: seishuku on 01:07:37 PM / 07-Oct-07
The garage isn't far from the house, so running a 220 line wouldn't be bad, just dig a trench and drop the line, hook up a few wires, done.
Just need to figure out a pair of breakers in the box for it (the previous owner kinda fucked the electrical), so I donno about that one, other than maybe an aux breaker box, but I don't have the money for more copper right now.

But you say it'll run on 120? What's the current draw on that beast? Phase?

It's no big deal, since we have all the equipment at work for doing it, but it would be cool to have some good stuff at home too!
Title: Matt's S12
Post by: Nemisis on 09:48:53 PM / 07-Oct-07
I was gonna say, if ya want, I got 2 welding machines in my garage, nice bench area to work, so if you wanted to make a Saturday all day, I could even provide beer.

Eh, whatever.

Fall meet sometime? Maybe once it starts feeling like fall- rofl!
Title: Matt's S12
Post by: 200sxkitcar on 10:41:19 PM / 07-Oct-07
Hell yea we should.  Nemisis is alot closer to you, his welders might be easier to use... mine runs around 15 amps input at the highest it can go on 120V which is 150 amps output, more power than you really need for most stuff.  The phasing, it can also auto-sense, I have only single phase, and it works fine.  If you had thought about picking up your own, figure on having a solid $3500 worth of dime, mine came secondhand  but it is portable and I can take it and use it up there at any time   The whole machine is about 40 lbs.

I like the non-fall weather   And I like beer even more   What welders do you have?
Title: Matt's S12
Post by: seishuku on 06:02:22 PM / 09-Oct-07
My personal welder is a Lincoln "Handy MIG" (cheap, but gets the job done for a 120v suit case), at work we have mostly 450AMP Miller machines, though some of the ones we use for finish welding were made in the 60's, Miller and AirCo.

We do have some more modern Miller Maxtron 450's, two are being used now, after I resurrected them.

Our TIG setup is Miller too I think, I don't remember what cooler it has on it.

We use to have a REALLY old Lincoln welder supply that was all set up to do TIG in my work area, but then they moved it to the other shop.

It's not a big deal to have to take the stuff to work really, I can use any of the equipment there when everyone is off on break or lunch.

I'm always up for another meet, just name the time and place!

Post by: Xano on 05:00:05 PM / 24-Nov-07
I have personally rode in this beast.

I gotta say, its a hella fun ride, even at only 8 lbs of boost instead of the 10 he started running later.

although you have to watch out for the damn ecu in the passenger floor boards.

good ride man, hope to see you again in the spring.
Title: Matt's S12
Post by: Nemisis on 09:10:13 PM / 24-Nov-07
Yea, but you didn't experience the speed and power I did- and I nearly shit myself when I saw the speedo still rocketing up. We're not sure how fast, but it was over 100 and the motor just kept pulling like no tomorrow. I mean I was still slammed back in the seat from the acceleration Gs... And the minivas we passed looked like huge blurs standing still. That was at 8psi, after we had to pull over and wait for Garrett cuz he was running on 3 cyl. Then he turned it up to 10. Fun fun fun!

Title: Matt's S12
Post by: seishuku on 11:22:09 AM / 27-Jan-08
It's pretty nice with just the DE, it's got awesome power, but I wanted a turbo too... So this has the best of both worlds! The turbo kinda needs a rebuild, but I think I might go with a smaller GT28and use the old T25 for a gas turbine engine or something.

Here's a pic of water tank and pump, including the nifty hammer arrestor that keeps the pump's pulses to a steady flow and also acts as a kind of pressure tank, so the pump only actually pumps every once and awhile.

The power to the pump is controlled by the relay for the fuel pump, so the water pump can only pressurize when the fuel pump is also on.

awesome project, looks like a lot of hard work. What did you use for intercooler piping? is it an s13 kit?
Title: Matt's S12
Post by: seishuku on 08:32:23 PM / 07-Apr-08
The intercooler piping was an eBay S13 kit, but it's pretty much universal.

Sterling, I don't have an actual picture of it, but I'll get one and post it up. However, the battery is 7x3x6, 680 max cranking amps (warm, don't know about CCA, probably in the 200 range, really needs a tender for winter use). About 15 LBS, and can't explode! (drycell)
The mount for it is just a piece of aluminum flat stock (1.25"x0.125") that I bent into the shape of the battery with some mounting flanges.

Trying a new setup, blow-through MAF this time. I don't know why I didn't do this in the first place, it's awesome! I had to relocate the water injector nozzle, but other than that, it idles perfectly and runs just the same (feels like a little more power too).

My biggest issue originally with this setup was oil from bad turbo seals, but after running this turbo for about a year I haven't noticed any oil in the IC piping, so whatever.

The pics!

The knock-off Greddy BOV sounds like crap vented, but the car overall does seem to run much better.

Now I just need to ditch the crap-tastic Walbro fuel pump for a nice Bosch 040, and I'll be set!
Title: Matt's S12
Post by: Nemisis on 03:08:01 PM / 11-May-08
Probably should have placed the BOV closer to the TB and it probably wouldn't sound as bad... Because closer to the TB is apparently the proper place for it. But looking at your setup, it seems like you were just working with what was already there- and it looks good too! Props on the valve cover man, cant wait to see this car again!
Title: Matt's S12
Post by: seishuku on 06:53:21 PM / 12-May-08
Yeah, that would be better, but there's just no room!
Maybe if I got the BOV flange welded to the piping, then it wouldn't be a big deal, but I wouldn't put that welding job on my worst enemy! 1/16 aluminum piping sucks to weld.

I donno man, that stuff came off pretty easy, even in this 80 degree heat. The only spots it's really sticking, is where the factory seam sealant is at, but that's gotta come out the hard way anyway.

And I haven't had many problems with stock sus... Other than the rear springs... *cough*Sterling*cough*

I updated to the newer version of eMachineShop and I have AutoCAD, so I'm gonna really start crackin on those rear control arm and redesign.

Plus this is all budget, one piece at a time and doing whatever I can for free... It's an S12 after all.

Hey Sterling, you know how my steering wheel gets sticky? Well, after having to peel my hands off the wheel after the meet, I decided to take off the really bad factory leather cover, and under it is actually a pretty nice rubber wheel!
Looks brand new!

No more sticky wheel, yay!

Oh, and an interesting note... The sheer bolts that hold the steering column lock on, those are really easy to remove by spinning them out with a hammer and center punch.

I think I'm going to get a quick release wheel and strip down the column.

Made my own ball+spring boost controller, set it back to 11PSI... Pulls HARD now, not that it wasn't before anyway.

Post by: SprockCapn on 04:24:05 PM / 16-Jul-08
I had a question about your boost controller. Does it have a "vent" hole on the side of it or just the ball and spring to restrict it. I made one that sounds similar but was told to drill a tiny hole in the side. I was just curious cause the "vent hole" whistles louder than the turbo and i figure it basically is making a boost leak. Thanks and Your build is lookin sweet. I like the white steelies
Title: Matt's S12
Post by: Arro on 04:30:16 PM / 16-Jul-08
A ball n' spring type MBC needs a vent hole of some kind to unbind the pressure on the spring each time you let off the throttle (and the boost recedes).

How big of a hole did you drill? A small enough hole doesn't make a whistle. Maybe yours is too big? What drill bit did you use?

I'm sure there is some sort of wrap that is non-conductive, but then again, pretty much anything is conductive at 30thousand volts, lol.

Eh, as long as your wires aren't shitty or getting old, you'll probably be fine.  If you have issues, it will be easy to check (just watch it run at night)

Yeah, I'll test that later, the pipe I have in there now doesn't arc, so this one shouldn't be any worse (sits about the same).

I gotta extend the pipe at the BOV flange, appearently I cut it about 1.5" too short.

Well you can find those breathers everywhere at auto parts stores for like 10 bux or less.

As far as something falling into the BOV, the thing shuts... It's not a big deal. Maybe dust going in, that's about it. B ut nothing dangerous can fit through the valve when it's fully open much less shut, and when it's not venting, it's shut.

From riding in that car a couple times, and knowing how it feels- I'm guessing you had that up around 70?

Oh, and from what I know about BOVs, they are louder when you put them on the turbo (hot) side, and quieter (as well as more responsive) when placed on the cold side.

My god that car hauls ass tho!!!

I actually got that from Kyle when he came over once. I didn't have a use for it at the time, so it just went in my goodies box. Then when Matt showed up for the meet and everyone drooled at the beast lurking under the hood, I noticed that the breather hose coming off the valve cover was just a hose. So I offered up that filter as I really had no use for it. Hey, I'm happy someone can use it.

Well, it's a good thing I started to remove sound deadening stuff... Found a area of rust under it, covered most of the area under the driver's seat and the rear foot area.
Nothing rotting through, but it was close... I bet it would have been real bad if I had let it go past this winter.

Also found a LOT of moisture under the material in the driver's side foot area and in the rocker box as well (visible through the large hoses with the tape over them, you know what I mean if you've ever taken out the carpet).

Nice.  How stripped is ur car?  I kno no dash but HVAC still at weighing?  How much interior?  Sound deadening?  Just tryin to get an idea how much my car will weigh.
Title: Matt's S12
Post by: seishuku on 11:00:15 PM / 10-Aug-08
No dash, no panels, no sound deadening (well, not much left anyway, just a few spots), no AC (still has heat), manual windows, no sunroof/moonroof.

Oh, had more than half tank of gas too.

It actually weights quite a bit more than I thought... I was thinking around 2500 at the most, high 2300 at the least. 2600 is surprisingly high to me.

Probably doesn't help that I have all original 15" steel rims.

I gotta make all new suspension parts, some 4130 alloy tube steel control arms, light weight struts, tubular sub frames, alloy rims, remove the sheet metal (like the spare tire tub).

 That's a lot of work for a few hundred LBS.

Good luck to Sterling on his 2200LBS S12.
Title: Matt's S12
Post by: IggyEGuana on 11:13:19 PM / 10-Aug-08
I C.  I have the same steelies on standby.  I've changed tires out on them at work (Goodyear) and those things are HEAVY!  Even for steelies.  I've had big ass 17in truck steelies that are lighter than ours.  Rediculous but at least its weight thats easy to get rid of.

I think the higher than expected weight has something to do with all the stuff goin on under the hood.  Mayb non-turbo on the bottle and you can get the kind of weight ur lookin for while keepin the powar.

Oh and the HVAC stuff under the dash (under nothing for you) plus the firewall sound deadening was 43 lbs out of my car.  You'll have to give up heat though.  They have little electric ones that run off the cig lighter.  Just an idea.

Post by: 200sxkitcar on 01:20:38 AM / 11-Aug-08
Complete loss of heat really isn't an option here, esp for a dd.  Unless you are a polar bear.  In extreme conditions, my S12 would have a hard time heating the interior up, and thats when before it was stripped.  We're talking temps less than 20*F, which happens with some regularity here.

Matt, that 2600 number is with you in it, I'm talking just the chassis.  Then, you would be closer to that number.

You SO have to tell me where this is, so I can get a decent measurement when I'm done!!!
!!!

So excited to know where a scale is  

I'm thinking 2300-2400 will be within easy reach, if I take care of a few small things with my setup (power windows, the damn sunroof).  That, and compared with your setup, you're looking at me not having the turbo, intercooler, misting setup, etc, so we should be fairly close I think.  Yep, 2200 will be a bitch, thats for sure

Been diving into the machine code of my ECU's programming, and I think I may have figured out something that will be worth while.

I'm not sure how familiar anyone here is with the more modern Nissan ECU, but they use the sensors (CAS, coolant temp, and MAF mainly) to calculate a value they call TP (theoretical pulsewidth) and that looks up in the fuel and timing maps along with the RPM value, that in turn gives you the fuel trim and timing for that cell (they also average on a 2x2 block for smoothness).
Anyway, the consult connector on most ECUs lets you access some of the sensor data, but they don't help any for tuning (maybe ignition timing, that's it though)... HOWEVER there is a RAM address that holds the magic tuning TP value AND you can modify a table that holds the sensors that consult reports.
Guess what the means? I can ADD the TP value to the sensors that consult reports and I can log all that!

Pretty sweet when you're on a dyno and want to log all that info for fine tuning.

That sounds pretty cool, but I understood approximately 30% of that.  Obviously, I have a ways to go in the computer tech department.

How you tuned your car initially, did you do it thru some sort of consult port that you wired in?  How exactly are you reading out of a consult port w/o the consult?

I used SR20DET maps for a baseline tune and went from there, the rest was done on the street with a lot of logging and my awesome Innovate LC-1 wideband and SSI-4 aux box (allows other inputs, RPM, MAP, etc), I love their products.

Reading the consult is easy, there are a ton of programs and adapters that let you connect a PC to the ECU, I actually made mine out of an old special cell phone data cable (it had a serial port adapter built-in, was perfect for the ECU).
I use Calum's latest version of Calumsult, and LogWorks 3 (which Calumsult can stream data to). I also have Nissan Datascan, which I paid $30 for a license to, but it has more of a dashboard type interface and better diagnostics options (I use that to figure out problems more than tuning).

I'll have to show you when you're here, it's pretty cool.

Exactly!

You should see what some guys are doing with 1990 Stanza U12 KA24E ECUs, they've actually managed to rewrite most of the firmware and even added consult capability to it! I might even switch over to one of those if I hit a wall with my current ECU (not likely, but you never know  ).

My tuning dashboard that I work with... Latest version of LogWorks, running the LogWorks enabled Calumsult (which streams consult data to LogWorks), and I've modified my ECU firmware to stream the TP load value to consult.
Which means I can log that in LogWorks, and generate a chart based on TP, RPM, and WB O2, then compared that with my ECU's fuel map and correct fueling!

A KA I picked up from Sterling.

Had a broken cam cap bolt on the head (fixed now), and right now I'm just kinda mocking up parts on it. I'll probably reassemble the long block, until I can get a new head gasket and some head bolts (maybe studs, donno yet).

It'll probably be built as a 9:1 CR turbo engine, but I may just build it stock as a spare engine.

Eh, most of the electronics cross over between the two, and the only thing on the drive line that needs to change is the bell housing. It's not as big of a change as it would seem.

I thinking of making this whole thing modular, so I could pull one engine and drop in the other with relative ease.

I'll probably have to pick up an S14 KA distributor though, since that has an internal coil like my SR (makes the swap easier).

The KA will however have all emissions intact and keeping the swirl control butterflies (keep some low end power, like my SR's VCT).

Picked up some goodies from my Brother:
 ), and a Blackstone intercooler off some SAAB... Basically the same as those Volvo intercoolers that some guys run on turbo S12's.

Edit:
Oh, and please no comments about the mess, I'm working on it, and I'm very lazy.
Title: Matt's S12
Post by: Arro on 12:50:52 AM / 01-Oct-08
I don't recommend the Volvo intercooler because the core is thin and tall... and you're only going to be exposing small areas of it due to the design of the S12 bumper. At least with a thicker core, that bit that's exposed is flowing more air through it. At the very least, get it pressure tested.

not to burst any bubbles but those ICs with the plastic ends are junks. They crack or even pop off when boosting any amount of air that really would require an IC lol
Title: Matt's S12
Post by: Arro on 02:29:59 AM / 01-Oct-08
Very true... and the cracks in the plastic aren't always visible or even easy to spot with pressure testing until they see some heat from the turbo air charge.

But the other point I made about the core design is a big deal, too... the S12's airdam is so limited as to what it exposes, you want a THICK core so that what IS exposed is flowing more air. This won't get that. Also, this is going to have to go IN FRONT of your radiator, because there is no way it will fit in the bumper. MAYBE with some GOOD powerful electric fans, you can stuff this in front of the radiator and behind the core support, and the fans will help draw air through it. Maybe.

Still, I don't recommend this unit.
Title: Matt's S12
Post by: seishuku on 03:46:17 PM / 01-Oct-08
Ducting is your best friend! The area that's exposed on the front of the S12 isn't a huge deal, as long as the air is directed properly.

And with the surface area on that thing, it's about as efficient as the front mount I already have. Plus it was free, and low miles... Though I haven't looked it over yet, it's practically brand new.

I'm not too worried about the plastic breaking or the tanks popping off, at least not at 11PSI... Maybe at a bar, or 20PSI.

Have you tried the kind with a magnet and you hit it with a hammer?
Doesn't work when putting it back together, but you can get it apart at least.

There's also a bridge type one that bolts to the head, and pivots on the bridge to push down on the retainer.

60MM, same as the KA, just a little different config (low-port high-port manifold differences).

I was looking for a slightly bigger one, but this one is already bigger than a turbo SR, so I guess I can't complain.

Edit:
Oh, when you come here, could you bring one of your spare rubber elbows, the one that says "AFM SIDE" on it?
Mine is getting cracked, and now has the old hole for the water nozzle... I really need to make a solid aluminum pipe for that part.

Editedit:
Oh, something cool about the S14 SR20 throttle body is that it has the cold idle function built in, so you don't have to deal with the retarded "air regulator" that always goes bad!
All it needs is a hose for the engine coolant. Nifty, eh?

OH, and I did some more work with the fuel and timing maps, revised them a little... Merged some fueling and timing from the stock NA map for off boost, and pulled out a little on the top end (was ungodly rich, about 9:1 last I checked)... And HOLY CRAP it was pulling hard today.

I know cold temps helps with boost, but still.
Title: Matt's S12
Post by: 200sxkitcar on 11:55:32 PM / 27-Oct-08
HAHA yeah, it seemed like you were a bit rich at times in the higher rpms (steps out of cloud of smoke & fire, LOL)  pulls harder than before?  shit!

k, cool, I'll bring the extra tube.  Now that you say that, and I look at the pic, its obvious its the same size as a KA, as that is the same hose I had on there for awhile

and being it is the same size as the KA, you could make that plate for others, I'm sure there would be some who are interested!  Waylon might be, as I think he was going with some sort of injection, this is a super clean way of doing it.
Title: Matt's S12

very cool man.  Not knockin it but I do have one concern.  With the injector at a 90 degree to the airflow and about 60mm from what is basically a wall.  Wouldnt deatomization be a problem?  Not sayin it wont work.  Just concerned it wont be optimal.
Title: Matt's S12
Post by: seishuku on 03:46:09 PM / 29-Oct-08
I thought about that too, but the nozzle is at the top of the butterfly (opens into the plenum) and the airflow (vacuum or boost, shouldn't matter) should grab the droplets and distribute them properly.

I can also make a port injection plate that would bolt in between the two intake halves, that was the original plan, but this was quicker and I still need to order the 4 new nozzles.

I could make a port injection plate for you if you want, but you'll have to make a 1:1 scan of the plenum flange on the CA18DET since I only have a KA and SR.

Another one bites the dust...

Lost another parking brake cable. Water got in it, water froze, thawed, rusted.
At least it was just a rebuild I did, using one of those parking cable repair kits.

Oh well, another item to add to the "to do" list.

Still have the other caliper to use anyway, just got the other end tied off to the subframe, so the lever still works the one side.

Not that I'm having issues with oil and such, but I made my self a catch can:
(https://i.imgur.com/KBdqoeY.jpg)
I know, that weld on the top is a little gnarly, but I had done that on the old Miller 330 A/B TIG machine and was having problems getting amps low enough to keep a good arc with out blowing through (it's very thin stainless steal).
The rest was done on my Miller MaxTron 450, which has much finer control, and would have came out much nicer.
I also need to wire wheel it, it needs a good cleaning.

What's inside:
(https://i.imgur.com/3htqCW6.jpg)

What it does, is the oil/vapors enter and the stainless steal scrubby pads and literally scrubs the oil particles out of the air passing through.
Title: Matt's S12

Title: Matt's S12
Post by: seishuku on 08:39:16 PM / 11-Feb-09
The two on the side are in/out, the top is just access (for emptying and to stuff the pads in), but I guess it could be made an active drain as well.

some of them might work intermittantly, remember I pulled them from the garbage... look carefully at the wires, particularly as they pass into the actual control, they tend to break there, so it would simply be a matter of shortening them and resolder.  otherwise, I can't image the other components in those are that complicated, it would be a matter of testing them electronically to see which had given out.  I imagine either radioshack or other electronics suppliers could get the rest of the stuff, if that was what the problem was....

catch can looks badass man, toss up some pics when its installed

also, lmk if you want the KA's exhaust mani and flywheel, they are currently at my aunt's house, I can stash them at the new place if you think you'll need them eventually...
Title: Matt's S12
Post by: seishuku on 04:07:55 PM / 23-Feb-09
Yeah, I noticed that some of the cables were a little rough. And so far one control wouldn't kick in the contactor, another would work if I wacked it with a screwdriver.
The one I'm using right now has been really good though, so 1.5 out of... 8?  Not too bad.

New exhaust time!


I've been getting a little annoyed with the side exhaust and cabin noise... It's been a long time since I've had a proper exhaust.

Edit:
Oh, and don't worry about the KA stuff, I'll be going with a light weight flywheel and a clutch that will hold more power. Plus it'll likely be a turbo engine anyway, so I'll need a turbo header.
Either that or I'll maybe make a shorty N/A header, I donno.

She has a full exhaust now!
I finished the main piping last night at about 11pm, which is when I normally go to sleep... And had to be up at 5am.
I thought about taking it to work with no muffler, but I decided against it and took the Scion. It's a good thing I did too, because I made a quick run to the pet store today and DAMN it's WAY louder with full pipe than it is with a short open tube.
Sounds hella awesome though, will be perfect for the track... I usually can't hear my exhaust over every one elses.

I'll get some pics of the exhaust later, since I have to take it back off to clean it up and paint it.

Oh, the flanges I made up from some scrap steal at work... A little plasma cutting and a little lathe/drill press work to finish up.
They only match each other, but that's all that mattered to me, they seem to even seal pretty well with out a gasket.

Also, the pipe and flange end on the over frame/under axle section doesn't quite fit through the stock location, so I have to unbolt the diff mount and drop the rear of the diff down to clear room.

I'm curious too. When I first read this I thought you were saying that you drove it to the pet store with it open dump pipe and that would make sense of it being louder, but reading that it says full pipe it is louder I'm curious how that is?

Post by: seishuku on 04:24:59 PM / 27-Feb-09
I mean the exhaust with out the muffler is louder than with no exhaust and just the O2 dump. I think the exhaust piping is acting like a megaphone of sorts, making things louder, it may also be causing a scavenging effect that pulls sound as well as gases.

It's hard to say for sure, at least not with out doing some tests anyway.

I wish I still had a dash, but I bought the car from Sterling with no interior.
It came from Arizona, so the body has no rust, but the downside is that EVERYTHING that was plastic inside was cracked or damaged beyond repair.
Originally I wanted to strip it down anyway, but I still wanted to keep a stock dashboard and customize it. I've been keeping my eye out for one, but shipping is crazy for one and I can't find one locally.

It's funny because either you get a nice body from a dry place or a nice interior from a humid place. CA has to be the only place with the perfect balance.

We have the same problem here, they always over do the salt during winter. Although, this year they did use sand more, but that doesn't do jack when they lay it down before it snows, then it just gets covered.

Hey, yeah, I didn't think of that... I might take you up on that.

Can you pull any part off, or is it a pay for the part kind of deal now? (since it's in the wreckers)

I'm not sure exactly when I can make the trip, gas money is a little tight ATM, but like I said before, probably after the vegas trip.

Edit:
Well shit, it's only 130 miles... That's not too bad.

I'll let ya know!

its a pay per part deal, but i know the guys at that junkyard well, and since its my car, I can work shit out somewhat.

smaller parts we can pocket/bag, they wont care.  I took about 30 lights from em the other day off of their 10 neons while i was there getting a taillight housing for my girlfriends car.

yeh, the place is decent on prices, generally their rule of thumb is any body panel is 25, any interior panel is 25, and if you just pull a bunch of small shit, like a switch or something like that, its usually free or 5 bucks.

Cool.
The Wife tells me that it'll have to wait until after Vegas, so hopefully everything will still be there when we get back.

On the ECCS issues topic:
I made a ROM with the knock sensor disabled, so far everything seems good.
My current theory is that when the engine gets up to temp, the heat is just enough to affect the piezoelectric element in the knock sensor and it causes erratic output.
OR, the ECU is ignoring the knock input UNTIL the engine is up to temp, and the sensor is just plain bad and causes the ECU to dump right into the knock maps as soon as it starts listening to the sensor.

I'm going to hook my laptop's mic input to the knock sensor and take a recording of the engine at temp, see what's really going on.

I know the engine isn't really knocking, it would be way obvious if it was (I'd hear it, or it would show on the spark plugs).

That's two sensors that have crapped out on me now, first my wideband and now probably my knock sensor.

I was wondering about this too. Seems like you would have more room and not have to cut much if you flipped it so the outlets were not running into the frame rails.

knock sensor being bad seems like a thought, It probably DOES ignore it until up to temp, and then when it tries to read from it, its getting really off readings but not recognizing it as the sensor being bad.

On the car, man, I tell you what, i'm the only S12 driver around here, so I'm the only one that grabs parts off it.  When i get paid, I can head down there and try to remove it, I just dont know enough about it to actually get it off lol.

They don't run into the rails, the piping will be right on top of them. It'll make more sense when I get it done.

Well, while inspecting some odd fuel pump rattling noises and engine off pressure loss issues, I discovered that my fuel sender wire bulkheads are about to finally fail.
Great.

So, now I have to find some place that sells some wire stud bulkheads that I can use. And it's the weekend. Ugh.
Title: Matt's S12
Post by: 200sxkitcar on 01:01:20 AM / 19-Apr-09
iirc keith did something like drill out the rivets and run the wires thru with some sort of sealer, this might be an option...
Title: Matt's S12
Post by: seishuku on 01:39:34 AM / 19-Apr-09
Already got a fix!
I couldn't find anyone that sells an isolated bulkhead stud, so I hacked together one my self (kinda).

The hardware used: A rubber sided flat washer, a 1/4-20 well nut, 1/4-20 x 1" bolt (grade 8, but doesn't matter, that's just what they had  ), and some nuts.
(https://i.imgur.com/MkSsK5o.jpg)

Take the bolt, grind the head to remove the cad/zinc coating, get it nice and hot and sweat it with some solder, and solder a nice piece of wire to it (12ga wire, with a ring terminal on the end, in my case).
(https://i.imgur.com/bPf3UIo.jpg)

Then remove and drill out the original hole to 7/16", then put the flat washer over the bolt and screw into the inserted well nut until it's expanded well enough to seal.
(https://i.imgur.com/UX2POFR.jpg)

Then just make up some new wires with some ring terminals big enough for the new 1/4-20 studs, that are now sticking up from the sending unit.

Also, here's the monster Bosch pump that feeds my hungry SR:
(https://i.imgur.com/SCH7X7l.jpg)

Really sweet unit, flows more than a Walbro 255 and can produce enough pressure to run 5bar if you want! Not too expensive either, and is a perfect size for the S12's basket.
Title: Matt's S12
Post by: seishuku on 04:18:47 PM / 21-Apr-09
It's kinda funny, I didn't do a full rewire on the pump (just at the sender) and now my power band seems to be way more consistent.
Before at WOT it would kind of chug and fall, but now it holds power right to the rev limiter.

I think I'm going to do a full hard wire on it and see if it improves even more.

All I did was put heaver gauge wire at the pump and from the sender to the chassis harness connector.
Title: Matt's S12
Post by: seishuku on 10:37:05 PM / 27-Apr-09
Made a hard wire harness for the fuel pump, just gotta install it.

Also, my brother gave me a MegaSquirt 1 to play with... It's pretty cool, though honestly I'd rather stick with Nissan ECCS programming, just seems easier to me.
I think I'll make an adapter setup for it and try it out on the SR, but I might just use it on the KA when I get it put back together.

Title: Matt's S12
Post by: seishuku on 11:44:33 PM / 27-Apr-09
Yeah, stock wiring isn't usually enough for bigger pumps and doesn't provide enough voltage.
Newer wire and heaver gauge allows more current and wiring it right to the battery (with a relay of course) gives more direct power, which will give you more constant fuel flow and pressure.
Title: Matt's S12
Post by: seishuku on 09:11:39 PM / 28-Apr-09
Got the hard wire done, works well. It MIGHT have made some change, but I won't really know until I do some data logging (CONSULT ).

Did an unscientific test, and did a 0-XXX pull between two 1/4 mile markers, hit around 110 crossing the marker... SO, if those are accurate, I should have just done a mid to low 13 sec 1/4 mile pass.

Neat.

I gotta replace the rubber on the drive shaft support bearing, make that solid.
Install my solid rear sub frame, and install a semi-solid trans mount.

I've noticed that while accelerating in lower gears, that I can feel the trans actually pulling down through the shifter... So I'm loosing torque there and that's no good!

Eventually yea, but I gotta do what I can with what materials I have on hand (scrap material from work), keep it on the cheap.

That mount was a piece of poly plastic we had at work, just happened to have the right drilling and all I had to do was split it and grab a few bolts and hardware.

I bet the best solutin would be to ship you a lower mi unit out of a car out here.  my time is super limited, but I'll let the other members know.  just grab the front half of the driveshaft, and swap.  the part itself is $18 here...
Title: Matt's S12
Post by: seishuku on 03:52:47 PM / 14-May-09
Oh, if I'm gonna replace it, it'll be with a brand new bearing and bushing ($60 later).
But I have a plan to replace the rubber part, I just need to take some measurements.

Edit:
Actually, there's a separate part number for the rubber piece: 37525-W1010
It's only $10, but I'd rather make a solid plastic piece.

Edit 2:
Hm, maybe not... I guess that's just a rubber cushion that goes around the rubber on the bearing. WTF?

Title: Matt's S12
Post by: seishuku on 12:24:55 PM / 16-May-09
I donno, it looks to be pretty decent enough... It's not BAD per se, just more slop than I would like. I'm pretty sure I could pull it apart with out any issues.

The big problem is unbolting the shaft from the diff... I've tried to get those bolts loose, but I just can't get a wrench or socket on them.
Title: Matt's S12
Post by: seishuku on 03:01:52 AM / 17-May-09
It's 3am here, and I just finished installing the welded diff...
I couldn't get one of the stays to come off, so I was only able to remove one half shaft.
Obviously this made things about 150% more difficult, but I managed.

One of the bolts are frozen solid, I think I may have to replace the control arm. Eek.
Title: Matt's S12
Post by: 200sxkitcar on 04:28:45 AM / 17-May-09
the control arm bolt being frozen is normal, even if its in good shape.  the best way I found going about it is to carefully (if possible) grind off both ends of the nut/bolt combo, remove the control arm, burn/press out the bushing, and reinstall with new bushing/bolt.  thats how I've removed them before...
Title: Matt's S12

Title: Matt's S12
Post by: seishuku on 02:18:00 PM / 17-May-09
I mean the forward bolt that holds the shock bracket on, it's locked solid... I'm going to try soaking it in some pen. oil and see if it'll free it up, otherwise I'll just break the bolt and weld a new nut on the control arm.
Though I do still have the one control arm that I got from you Sterling, it's the same side (driver's), so maybe I'll press out the cut bolts in that and just swap the arms. I donno.

I just drove it with welded diff... Didn't even notice it at first. Tight corners are a little harder to turn, but maybe I'm just used to that with out power steering.
Like Waylon said, just give it a little more gas.

I was kinda wondering myself if the gas would kill the rubber you used.  I'm sure you could find a rubber/silicon one that is gas-resistant though.
Title: Matt's S12
Post by: seishuku on 06:12:44 PM / 18-May-09
Yeah, it's just rubber and it'll swell from the gas and eventually rot out. But I'm not sure if they make the same parts only in nitrile rubber.

It should be ok for the most part, it's not constantly in direct contact with the gas.

I got all the bits from Menards, but I'm pretty sure most hardware stores would carry the parts.

I just did the same setup on the other hole, it's just one for positive and one for negative on the pump.

I hardly notice it, except when backing up while turning... You get that one wheel that's skipping and bouncing around, making the suspension make funky noises.

If you don't have $600 to lay down on an LSD, this is nice if you have a spare diff!
I don't like thinking about the stress it puts on the axles while turning (see Waylon's thread ).
Title: Matt's S12
Post by: seishuku on 11:36:29 PM / 25-May-09
Got a neat front suspension trick for you go-fast guys:
Take the tension rod assembly apart, swap and reverse the bushings, and flip around the large washers, then reassemble.

What does this do? Well, the two bushings that make up the rod assembly are two different thicknesses, so if you place the thicker one on the rod end (towards the rear of the car) it will push the caster slightly more positive. And the large washers? Well, that will just tighten thing up, keeping things more solid.

Neat huh?

I was getting sick of my S12's high speed stability, so I was looking for a quick fix (seeing if the bushings were shot), and noticed that one was thicker than the other.

Results? Well, let's just say it will return to near straight by it's self now (quickly too), and it's VERY stable at 90+.
I can actually cruise at highway speeds with out having to constantly correct it.

I'm sure new bushings would be a bit stiffer and would help out, but I'm cheap. Even though they're only $10 each.

Yeah, I saw that, though personally I don't know about the life of those bushings. The tension rods really need a flexible bushing or a spherical joint of some kind (S13+ type).
Also I'm cheap, this was free.

It was raining a lot here just now, so I figure "hey, why not make a pit stop at the old mall parking lot?"... Well, I guess either I really suck ass at drifting, or my tires have way too much grip.

It was an old worn cement parking lot, so it's really rough, which doesn't help much. Heh.

That's what sucks, we don't really have any big open parking lots that I could just rip around in... At least none that I wouldn't get in trouble with.

And they are all the crusty cement lots here too, hardly anything is asphalt.

Oh, trust me, I don't have grip issues in rain... The only thing these tires aren't sticky in, is snow.

I'll probably toss on the alloy rims with the junk tires (nearly bald from the burnout pit last year) and try again later.

On another note, I need to put the other radiator fan on I have, I hit 200F in no time with the fan on, just screwing around for a few minutes.

Power steering redux:

Title: Matt's S12
Post by: seishuku on 12:21:02 AM / 13-Jun-09

I guess that fitting did seal, but I neglected to tighten the return hose.
At least it wasn't the pressure side, that could have been a mess!

Oh, and I know that it doesn't look like ATF, that's because it's not. It's actually some left over 10w30 Mobil 1.
I don't really care, it won't hurt it any, plenty to keep things clean in that oil.

i pretty much learned to drift in the rain in a low power car, its so easy to stick it where you need to, even dropping the outside tire in a ditch  but, definitely smoother surfaces are easier to control the car on

howre you liking the ps? the s12 doesnt have much angle stock, you could put some lockwashers on the inners to increase angle and effectively, quicken the ratio, aswell. i put some on mine a long time ago and they help out.

im curious how long the welded r180 will last with your power levels, i havent broken mine yet though with a stock ka
Title: Matt's S12
Post by: seishuku on 12:04:35 PM / 13-Jun-09
I do kinda miss PS, but I *just* put it back on and I'm still getting used to it again.

With my style driving, I haven't really needed more angle. I might do that when I rebuild some of the front end (new bushing and ball joints).

Well, the way I welded the diff, it should transfer more of the energy to the diff housing, since I didn't just weld the gears together, I also welded them to the housing.
So I'll probably strip the ring gear or pinion first, but I'm fairly sure I'll destroy the transmission before that happens.

Leaving the stock suspension in place, working the S13 adaption around it, since I plan on adapting the chassis to the new setup.

I got an idea of how I'm going to do it in my head, but the sus needs a little work. Brakes, rotors, ball joints, otherwise it's in pretty awesome shape.

I didn't realize that the R200 was so big, compared to the R180.

Interesting info about S13 rear brakes, they're the same model caliper as the S12, but the caliper bracket (the part with the slide pins) is a little different.
It's mount pads are flat compared to the S12's, which are raised (about 1/2"), and the S12's bracket dips in a little near the piston in the middle.

However, S13 rear rotors are identical and so are the pads.

So that means we can use the Z32 rear brake conversion just like the S13, it's just that we would have to space out the caliper to get the same alignment (washers or a nice aluminum spacer).

I think the only probably would be that the Z32 rear brakes might have the same stopping power as the stock S12 fronts, so I donno how that would work out. Heh.

That's true.
Though IIRC someone on here mounted a drum backing plate to the IRS control arm, by drilling and tapping it for the proper bolt pattern. I still don't know if I would trust it, but I suppose it works.

Title: Matt's S12
Post by: seishuku on 11:35:56 PM / 29-Jun-09
Taking some preliminary measurements, it's actually not too far off.

While the two suspensions have the same track width, the front mounts on the S13 frame are about 5" more narrow than the S12, and the front mount to axle center line has a difference of about 3.5".
Which completely misses the torque box for the front mounts, it does seem to nicely line it up with a rear cross support on the unibody.

Probably what I will end up doing, is removing the torque box up front and weld in a small C channel or square tubing, then do something similar out back depending on how much spacing it needs. Otherwise it'll just be a bolt through the support member.

Bigger issues would include drive shaft, and strut towers.

Nice thing about the S13 setup, is that the mount points don't need to be super strong, since it's distributed across four points. Unlike the S12 where it's only two points that take all the twisting force and using the diff for a stress member, really lame.

Yea, I'm still crazy though.

Actually, if you can keep your eyes out for some S13 rear strut towers, that would help. I don't remember if they're just spot welded in, like the fronts, I was going to try to find a part number and see what the price is.

A large rough cut with a torch or plasma would work too. It's not very thick material, only 14ga IIRC.

Let me know bud, no rush... Still got lots of time before I'll need them!

Gotta find either OEM struts or aftermarket coilovers, a new brake bracket, ball joints (though they might only need new boots), though pads and rotors I can reuse from the S12.

And I need to figure out something on the drive shaft too, which depends on where the subframe ends up exactly.

Other issues, drive shaft.
Stock S12 won't work, it's about 5" too short (long nose diff vs. short nose diff) and flanges are different (short nose R200 is MUCH larger and splines are bigger, so I can't just swap flanges).

The right thing would be to get a custom shaft made, but I can't spend that kind of money on it (not right now anyway), so I have another solution that I can do in the mean time.
(https://i.imgur.com/dfEMugz.jpg)
(https://i.imgur.com/JLAhzdF.jpg)

Now, the question is, should it be made out of steel with a through bolt flange, or should it be make out of a high alloy aluminum with taps for the bolts instead and the whole piece solid (instead of a smaller tube as shown).

I was thinking aluminum at first, but aluminum would be a pretty large chunk (about 4" od, 5" long), and obviously steel would be much cheaper.
Title: Matt's S12
Post by: Xano on 10:53:54 PM / 05-Jul-09
I'd do the steel, so it has the capability of possibly bending on failure, instead of completely fragmenting.  It would seem safer for the occupant =P
Title: Matt's S12
Post by: seishuku on 11:37:01 PM / 05-Jul-09
With as solid as the aluminum piece would be, I'd think it would have a u-joint fail or the flange bolts sheer first. I donno.

Other option would be to machine the mating flanges, then weld in a tube between them, much like a drive shaft.

Lots of options, I guess I'll have see what materials I have to work with.

The aluminum needed would be around $50 (4x5 round solid stock), steel would be about $40 of 4340 chromoly , and $30 for 1018 mild steel.

I might do the tube option, since I can make the flanges out of flat stock, but we'll see.
Title: Matt's S12
Post by: seishuku on 12:14:42 AM / 06-Jul-09

Yeah, I think I'll do the tube.

2" x 0.120" wall DOM tube is only $5 for the piece I need, and weld on flanges will be easy enough.
Title: Matt's S12

That short of a piece isn't going to affect balance, run-out is more of an issue, but that's what a lathe and dial indicator is for.

I did think of maybe trying an S13 rear section, but I don't have one on hand.

One third of the puzzle...
(https://i.imgur.com/v4owsrr.jpg)

Took the input flange off my spare R180 housing, machined it down to accept the ID of 2" DOM tubing. Once the tubing comes in, I'll straighten out the edge of the tube, press them together, then weld them.

I have to make the piece that mates to the R200 flange, then all that's needed is the exact length to add to the stock shaft.
Which should be the distance from the R180 input flange to axle center line, minus the R200's distance from flange to center line. (came close to 5", but I'll take a more precise measurement later)

Oh, of course. I'm gonna try to keep it to 0.001" or less run out, Nissan's max run out for the drive shaft is 0.024", so that will be more than good.

The pieces will be pre-machined, then welded, then faced off to maintain proper run out.

I'll probably spin it at the lathe's max speed to see what the balance is like, but like I said before, it's so short that it's not likely to mess up balance.

Yeah, Just cut em down the middle and pound them out, then take a deburring tool to remove the little lip they put on em. But then you need to fab a groove in there for a circlip. It works pretty nice, but is a lotta work.

Title: Matt's S12
Post by: 200sxkitcar on 01:33:58 AM / 17-Jul-09
looks like the springs were spec'd at 150 in/lb which is pretty close to stock, if thats what you want.  close to stock is ok for me for ride quality, but for handling a bit stiffer perhaps, just depends on your style/preference.

as long as the shock portion alone is replaceable/rebuildable  id say looks good...

14" springs are long, but it depends on the end setup...
Title: Matt's S12
Post by: seishuku on 03:59:40 PM / 17-Jul-09
Stock rears are 129, but being a 2.5" coil, you can pretty much get whatever you want.

The total length that I need is about 20" at full droop, for where I want to put the upper mount. Keep in mind, that the 240 rear spindles have the strut bolt on about 40mm higher than where the S12's shock bolts in, so it's quite a bit lower of a point than where the S12's spring seat is.

Stock S13 struts are pretty long at full extension.

BTW, do you (or anyone really) know what the full rear suspension travel is? I was going to pull out one of my rear springs today and find out, but it just started to downpour and the garage has 240 rear parts scattered everywhere.

Just for fun:

R160, R180, and R200.

The R200 isn't that much bigger than the R180, but the diff carrier is HUGE compared to the R160/R180 carriers.

I didn't take a pic of them, but the big difference in strength on the R180 and R200? Stub axles (though the spider gears on the R180 aren't very strong either). The R180 (which are integrated on the CV half-shaft) are well, tiny, about 3/4" in diameter. The R200 on the other hand, are damn near over an inch, they're monsters!

Edit:
Oh, and the R200 is going to work with me tomorrow, weld 'er up.

im not sure as yet..might be a lil bit of both...as ur'e thinkin im gonna use the rear cross beam of the unibody to mount the rear mounts of the subframe. then i MIGHT cut and move the front mounts to suit to the s12 trailing arm position. or i might end up moving the pins

Title: Matt's S12
Post by: seishuku on 04:26:02 PM / 23-Jul-09
Right now I'm going off the difference between the diff lengths, the long R180 from input flange to axle center-line minus the same measurement from the S13 short R200. It comes out to about 4.5", though I still have to get an exact measurement, which should be easier now since I have the R200 broken down right now.
But with that difference measurement, you can figure out how much longer the drive shaft needs to be, which will place the wheels exactly where they need to be under the chassis.

Which, conveniently enough, places the rear subframe mounts pretty much directly in the center of that rear cross brace. I think for that, it's just a matter of drilling a hole through the floor pan and through the brace and just use a carriage bolt (a really long one! ) and a large washer. Maybe a stay bracket like the front mounts use too, if it's needed (won't know that until it's test driven and shaken down).

The clip grooves on the R180 are set 52mm in, but on the VLSD R160 it's 38mm and 50mm.
The long side could be done, but the short side wouldn't because 52mm in is the viscous coupling.

I wouldn't mind trying to cut new ones, but we don't really have the tooling for cutting hardened materials.

Also, the half shafts are 1/2" shorter than they need to be, which might not be a big deal (the CV does stretch some) but with out proper clips, they'd probably pop out.

Cleaning up the backside of my stock alloy rims, they had some BAD salt corrosion on the hub bore and the back had a nasty mineral buildup.

I forgot to take a pic of it before I cleaned them, but Sterling might remember how bad they were.

Just picture this: The nasty salt residue that you get on your car during the winter, only about 1000% worse.

I used some industrial lime remover (acid blend) at full strength, which actually did etch the metal slightly, but it was the only way to do it short of actually blasting them.

Normally the gasket is painted, but it's been chipping off and the water+alcohol condensing on the runners caused it to seep into the bare metal and made it start leaking.
I figured it might happen some day, but I figured it would be a little while longer. Oh well.

It also tells me that I'm getting more alcohol in the #1 cylinder than the others, that runner had more blue discoloration than the others. I think it's time for a direct port injection system.

yeah doesn't that block the flow to the rad I thought that's why everyone used the airdam instead

Actually either way does, if you look at yours you'd see what I mean. It can't be helped, which is why it's popular to go with a better aftermarket radiator to better cool the fluid.
Title: Matt's S12
Post by: seishuku on 04:57:30 PM / 10-Aug-09
Yeah, the IC will block it either way, so I went with a mid point. It'll put in ducting and do a little flow diversion later.

The core is a tube+fin, measures 26x8x3 I think, not huge but I didn't need much either. I bought it specifically to fit between the frame rails, so the charge piping is short.
Does a damn fine job, hot pipe is hot, cold pipe is cold!

Yes, it's purple, however it's actually darker than what the camera makes it seem (flashes SUCK), plus with a tire on there will bring it down more, PLUS on a black car even more.

Just an test really, I had the RAL color so I figured why not. I can always have the wheel blasted and redo it with whatever.

Yeah, maybe. It's hard to do multitones with powder coating, at least with out making a huge mess.

I suppose I could use a wheel paint, but I don't like painting over powder.

Instead of my powder gun, I should look into getting some of that powder paint and just brush a different color on.

Also, keep in mind, there are still the chrome lugs that will show, and there's the center cap that I could do something with.

Here's a little bit better of a pic.

The two that held air still (the ones with firestone tires) were fine, just one had a chunk missing from the lip. They were pretty straight, and didn't even come out of balance with the weights removed (don't know how that worked ).

The other two I think just had really bad tires, because when I put two of my old Yokohama tires on them they were perfect, no odd noise, no noticeable runout.

They all could use some reconditioning, as they all have bad salt pitting on the hubs, and the lips are all beat up. But they do run straight.

I'd keep an eye on powercoated wheels. I had a friend powercoat STi BBS wheels and they now have hairline cracks all over. Powercoating rims is a big no-no in the Subie community. It's probably because of the powercoating process itself that causes the rim to do that. I haven't seen any other stock STi BBS crack except powercoated ones.

I finally got around to removing the last of the sound deadening material, only had the area in the passenager foot well, and driver's side firewall, as well as the area under the heater box.

I also went to reweigh my chassis, comes to 2380LBS... 2600 with me in it. I'm a fat-ass.  

Edit:
The last weigh-in I did was at 2630 (somewhere around page 6 I think), with about the same amount of gas (I think).
I don't think my weight has changed much, so I managed to drop 30LBS off the chassis.

Only thing is, I don't remember if I had power steering in at the last weighing.

Trust me, I've ridden with his "fat ass" and lead foot, and shit myself both times.

I just don't remember, we hit just over 100 in a 35 zone? Then he pulls over (needed to wait for Garret's KA S12 that was running on 2.5 cylinders) Goes under the hood for a minute then gets back in the car. I looked at him and he just said "I had to turn up the boost."

And with a turbo style muffler, the car doesn't even sound like its trying all that hard, its not that loud.

And that 100mph run was after tacos, on our way to have beer.

That was when I still had that POS Civic, the first Midwest Fall meet at Matt's place.

Temperatures Of certain types of powder coating are to high for certain alloys, because of there low annealing point.  When metal has any force applied to it the molecules start to over lap and move out of alignment this although making the metal more bridle also hardens the metal. Every metal has a annealing temperature,at this temp the molecules relax and fall back into alignment making the metal malleable once again.
 This can be very dangerous!!!!
 Iv seen some pretty bad thing from this happening.  Although heat wont make it crack after being annealed then exerting a extreme force on the wheel things could go very very BAD.

Just thought id throw my $0.02 in.

I have a couple Holsets at my disposal if you want one on the cheap. I have in my garage an HX35 Single scroll, a Dual scroll, and an HX45.  

Oh yeah... You've never met me. howdy

If you ever want colt parts. I have a hookup down in rockford. I found him a Turbo colt and he's been hoarding stuff for the past year. He's my go to guy with probe parts. some nissan parts. and expecially the old dodge turbo's. I have an Omni GLHS I don't like to discuss with some people. So you've got another hookup if you decide to take up on it.

EDIT: I forgot to mention. If you EVER want any 4G63T or ANY 4G63 parts. I have a neighbor with (no joke) 7 complete blocks, 4 Td05h turbos, Blue tops galore. He works at a local junkyard and grabs everything DSM he can. And he'll probably sell you a known good engine for like, 150-200 bucks. Then swap it out in my garage with his and my help. Get it done in a day

Definitely gonna hit you up on some of that shit. Pretty much I'll need to get the 1g DSM to 3g CSM adapter plug (one mess of plugs that directly adapts the DSM's ECU and harness to the CSM's chassis electrical so everything still works the way its supposed to), the swap mounts, maybe a radiator (mine looks like this will be it's last winter, although its better than many I've seen), a trans, and convert the clutch system from cable to hydraulic. There is a bunch of other shit too. Those are 1g 6 bolt or 2g 7 bolt?

The GLHS was my first car at 16. I've driven it twice. Once home with it, I wondered what the numbered badge was on the dash (#073) of which I found out what it was. and once to it's current storage facility, in a bubble.. A GTX, A very special probe (7th one off the assembly line), Had a Shadow Shelby, and a 1st gen neon ACR, But quickly tired of those and sold them.

Got a working Bosch WBO2 sensor from my Brother, so I'm back trimming out fuel again.

Ever since I put this straight through muffler on, I can hear the misfiring from over-fueling. The old turbo muffler that was on there was hiding it, apparently. Now I get machine gun fire from my exhaust some times. 10:1 air/fuel ratios will do that.

So the past two days I've been slowly data logging and trimming out fuel.

Title: Matt's S12
Post by: seishuku on 08:20:20 PM / 08-Sep-09
lol
I'm an idiot.

I forgot to copy the primary fuel map over to the knock fuel map (bad knock sensor), so my adjustments never were being used. No wonder the AFR never changed.

I just fixed it, back on the first try was spot on 11.8:1.
Now, I know that 12.5:1 is ideal for turbos, but I've also been told that more power can be had at around 11.8:1. I suppose I could try both, see which works better. I donno.

Yay, no more 9 and 10:1 ratios!

Edit:
Now, to get a bigger MAF, since that's been maxed out for awhile now (and probably choking the top end).
And get a turbo that doesn't choke out, maybe a smaller T3, or just a T28. Though I do like the spool on my tiny T25g.

I'm still working on the suspension! Tuning is free, parts cost moneys

Ponies I'm not too worried about, it's the foot lbs that I'm after.
It's defiently pulling better up top now, before it just kinda petered out and stopped, now it feels like it's gaining more power even at 6500+.

Yeah, still stock MAF that came with the engine, supposed to be good to 250 or 280WHP, so I gotta be close to that number.
I have a hack that might get me around the MAFS limits with out buying a new one, either by placing the element in a sized pipe, or bore out the stock housing. I'm not sure what I want to do yet.

New water tank for the alcohol injection, and could double for an alternative fuel tank too (though it wouldn't hold much fuel, about 3.5gal).

Baffled of course, and a bronze diffuser for a inlet filter. All 304 stainless.

Gotta do the cutout on the top for the access cover, and for the filler pipe.

Well, I didn't get the forward mounts in, because I can't with out removing the stock subframe.

I did lay the two suspension frames together, and take measurements.


It also places the rear mounts directly on the rear unibody member for the stock rear diff mount. Perfect place for some holes to be drilled and carriage bolts installed, with reinforcement plates of course (much like you would with a roll cage).

I can do the rear mounts, but the front will have to be done when the whole thing goes in, so the car will have to be down for a few days... Which means I will have to have everything ready to go.

I have recently come to the conclusion that I need to get more aggressive with my timing curves.

After playing with a friend's 03 (?) chipped Passat, I realize that I really need to get my torque figures up on the top end.
It's got a nearly equivalent turbo in flow (K03 vs T25G), but for some reason his 1.8T pulls nice.
Maybe I just need to get on a dyno, I donno. The tune his ECU has is well enough refined on a dyno (APR's "canned" tune).

I can tell I'm making more power, butt dyno can tell that (even with a 1000LBS chassis difference), but I need to up the ante.

It'll happen, I'm not about to give up on it!
I'll probably need the adjustable arms after I get it all in, but I'm not going to worry about adjusting it until it's functional.

Tired of your differential puking oil everywhere?
Try this!
(https://i.imgur.com/KWcRx7n.jpg)

Yank out the crap-tastic OEM breather, tap it for 1/4" NPT (the hole is already the perfect size), and put a 1/4" x 3" long pipe that's threaded on one end in it. Then tap the unthreaded end of the nipple for 1/8" NPT (again, it's the perfect size), and screw in a 1/8NPT 1PSI to 3PSI relief vent into that (such as McMaster-Carr part # 1093K1).

I'm really getting tired of my diff dripping oil everwhere, and it seems to be dripping more and more lately. I've tried resealing everything already.

Thank you captain obvious.

So far so good, no dripping yet. If it's going to, it'll probably take a few heat cycles.
I probably should have welded a baffle plate in there too while I was at it, but oh well. I can always do that later.

I also did an inspection of my diff, all the welds are holding just fine, no cracks at all. Good thing I know what I'm doing.  

If only I had the $6.79 to change the oil while I was in there, instead of reusing the old nasty stuff.

K04 compared to a GT3582R. Tried finding a pic with one next to a T25, but couldn't find it.

Ooops. I guess they came with either. They are TINY turbos!!!!

K04 compressor inlet size:

The K03 is just slightly smaller. I think its 1.3" or so.

And on my Ruckus scooter club, a couple guys with 150cc swapped motors can spool a K04 turbo... so far to 10psi. I can dig up some of those if ya want, there pretty cool.

Amazing that a 150cc engine can even spool that thing!
Doesn't sound like it's making much power though, I'm guessing those engines don't have much for timing management.

Not really. they run off of a CDI box. Pretty much a ignition timing computer with a rev limiter. And did you notice that we HAVE to run it as a draw-through setup... Sucks. But it works, and those turbos are pretty cheap and plentiful.

You'll like this (http://www.youtube.com/watch?v=xyU3UGYGVNg) too. Hes running a standard GY6 motor with a 4-valve head (stock is 2) cammed. Too bad you cant bore up to bigger displacements with a 4 valve. These motors can be built to 190cc.

Actually, factory management is higher res (ECCS is 16x16 tables, MS is 12x12), but it's just something new to play with. Lots of really nice features (anti-lag, auto rad fan, water injection, even traction control if you want), and shouldn't be too hard getting it up and running.

I got the timing map converted over already, just need to do something with fuel. Which is harder to do, since the ECCS sort of uses a percent over stoich and MS uses a volumetric efficiency percentage, but I'll get it.

I do need an intake temp sensor though.

Edit:
I should clarify, I have a MS1 v2.2, which is lower res than stock EMS, but MS2 is the same res.

It's not well tested though, and probably wouldn't work with a Nissan MAFS anyway (5.12v max vs. MS's 5v max).
I originally wanted to do that, but MS is designed around speed density, so I might as well use it.

Plus I'm already maxing out my MAFS anyway, so speed density is a cheap way around it. As much as I don't like it.

Title: Matt's S12
Post by: seishuku on 09:16:15 PM / 20-Nov-09
Oh yeah, stock ECCS is really flexible, and those guys are always making new breakthroughs on new things. The biggest things right now have been a complete rewrite of the KA24E ECU found in the Stanza (U12), adding consult to ECUs that didn't have support before, and built-in launch control.

Tuning is really easy, even if you do it the hard way, the other software that people charge for (like nistune) is really just for convenience (of course they offer other stuff too, like daughter boards), but you can make a daughter board and burn a ROM chip and be tuning!

Oh, another thing that pretty much no one knows, is the ECU that the RWD SR20DE and GA16DE (they use the same style ECU) is a really shitty designed ECU for reprogramming.
It comes from them integrating a lot of the logic and processors into a single solution, and it creates a problem when you want to use external memory.

Edit:
Oh, and big flow MAFS cost big flow cash, I'm cheap.

Made an intake air temp sensor for the MegaSquirt:


I plan on picking up an open element GM sensor later though, when I have money.

Hopefully I'll have some kind of running test soon, bare bones, but running. lol
I need to pick up some transistors for the options that I want, like the cam phase solenoid.

Then I'll get a new trigger disc for the distributor (probably an AEM style one), then switch over to a waste spark or full COP (if I can get some good coils).

I could use pretty much any intake temp sensor (though some won't take pressure), but I have the parts around to make it, so why not?
It'll work just as well as any other sensor, though the open element GM one will respond a little faster.

Initial run, to get some data.
My eyes are still kinda burning from the exhaust fumes, 9:1 AFR @ idle = BAD.

I'll get the IAT connected up (didn't feel like flipping around the intercooler), and get a solid idle later on, then work out the actual tuning.

Here's the stub harness I made. I just stick the wires into the stock ECU harness connector where they should go.
Eventually I'll probably just hack off the connect from the engine harness and wire it in, but I would really like to get an ECU connector and make an adapter, that would be awesome. Too bad the connector is like $50.

Also something to note when starting, it has a tendency to kick back, which is because of the signal from the distributor is only 4 pulses per distributor rev and is bare minimum for running MegaSquirt.
So it doesn't really have enough info from the CAS to properly sync the crank and cam events, but I will be getting a new trigger disc for the CAS that has 24+1 windows on it (24 crank + 1 cam sync), instead of the stock 360+4 disc (too much info for MS to handle).

Otherwise, it runs really well once it's tuned correctly.
It was able to trigger my stock distributor power transistor no problem, which I was a little worried about, but no issues. Probably will need to adjust dwell duty and time though.

After I get the new trigger disc though, I can switch over to full coil-on-plug ignition too.

Started tuning it today, it's drivable right now, though I have the arm off the wastegate, so I'm not going into boost ATM (for what should be obvious reasons ).

I forgot to turn down accel enrichment, so I was fighting that while working over the VE map... Then my laptop battery died before I could fix it.

Something weird though, I can't get it to start and run with using coil dwell, it'll only start and run with a fixed duty cycle.
I'm nearly 100% sure the stock power transistor in the distributor isn't a smart dwell unit.

It seems to run well enough with the fixed coil DC, but I'm not sure I want to see what will happen under boost.
Title: Matt's S12
Post by: seishuku on 09:55:52 PM / 03-Dec-09
Woohoo, I got the fueling 80% done!
The other 20% is fine tuning for performance, which will take a lot of time, a lot of data logging, and a lot of time.

It pulls way hard, seems more than it did with OE management, but I was having some odd intermittent issues with that too, pulling timing at weird times and such.

I think it was still running pretty rich on the OE ECU, MPG was suffering some, so I should be getting better MPG with the MegaSquit while in boost.

I'm really liking this, I think this weekend I might just permanently wire it in!

I just need to figure out why I can only get it running with a fixed duty cycle on the ignition, and why it won't start or run with a set dwell.
It's not a smart dwell ignitor, so I don't know what's going on here. It doesn't seem to be missing at all with the fixed DC, so I'm not going to worry too much.

I didn't really try too hard with the dwell, but in the manual they say dwell shouldn't exceed 4ms. I didn't try it higher, but it didn't work with spark inverted or not or with varying dwell settings.
I donno, I guess I'll just leave it until I get a new CAS trigger disc and go waste spark or COP.

I still gotta properly fix the fuel pump relay though, it's powered by the battery, and MS needs it to be ignition switched (otherwise when the MS powers off, all the outputs ground, and the fuel pump stays on). So I got it somewhat rigged right now, I'll fix it later.

Awesome, about time you made it back here!

I'm really happy with MS, so easy to tune. I'm actually making more power than I was with the stock ECU, because the AFRs are spot on now.

Sure, I could have done that with the stock unit, but it's a lot more work unless you have an ROM emulator or real-time board.

Wild guess who I am....  


Just remember: the longer you put off doing it, the more you miss out.  I kicked myself for not going to EDIS sooner than I did with the Corvair, it changes EVERYTHING.  Starts easier (your current problem), is more accurate so you can run more timing before detonation which makes more power, and there are no moving parts to wear so there's no tuneup costs.

Look at it this way:

Was I right about MS, or wasn't I?

I'm right about EDIS too, just do it and stop procrastinating.

BTW, welcome to the Dark Side.  I mean, the wonderful world of MS!
Title: Matt's S12
Post by: seishuku on 08:50:47 PM / 10-Dec-09
Gee, I wonder...

With a different wheel for the cam sensor, it'll time just as well as an EDIS, it would fix the hard starts too (since it would have a cam sync).

Though the multispark on the EDIS does seem like a nice feature, but wasn't that on only a number of units?

At least right now, the timing doesn't deviate too much, only maybe +/- 5 degrees from what I can tell with the timing light. Nothing it can't handle, especially with the water injection.

Oh... and haha, you're a sub-n00b!

Not really...

You don't need cam sync, are your pistons attached to your cam?  EDIS runs directly off the crank, so there is nothing to indroduce timing errors.  Things like timing belts, the internal parts of the distributor, and the distributor/cam mechanical connection itself all make the system sloppy.  5 degrees is HUGE in the grand scheme of things, and EDIS has 0 scatter that I can see with the naked eye and a timing gun.  That alone is worth the price of the conversion, trust me.  Like I said, you'll kick yourself for taking so long once you see first hand the difference it makes.

Quote

It's been said that some EDIS modules had MSD capability, but I'm not concerned about it. The main thing it brings to the table is dead nuts accurate timing, a strong stable spark, and no mechanical parts to ever wear out.  You don't even need the EDIS module anyway though, MS can run the coil pack directly with the appropriate driver circuits.

Read: http://www.msextra.com/doc/ms1extra/MS_Ext...ual.htm#2coil22 (http://www.msextra.com/doc/ms1extra/MS_Extra_Ignition_Hardware_Manual.htm#2coil22)

Or perhaps you'd prefer COP?  I have 2 sets of Ford racing COP's from a Harley edition supercharged F-150, if you like.  You would do it basically the same way as coil pack, but the wiring would be different because of the individual coils.  Let me know, I'll bring a set when I stop up today for you to look at.

Here's the COP info:

It's making decent power on it already, I already need more tire to keep traction as it is. I wouldn't be surprised if it's near 300bhp.

I don't think you're at 300 just yet, but imagine what it would do with some honest intake flow right?  You keep underestimating the potential of this thing, and I'm not sure I understand why.  There's no reason whatsoever to not push 18 PSI at this thing with a better turbo, other than the aforementioned traction issues (trust me, I feel your pain there).  Put that new rear end together, and I'll see what I can do about the turbo.

You have a 2-liter...and 16 valves.  That means T3 at the very least, if not hybrid T3/T4. Seriously, if my little VW 1.9 can spool a T3 so can you dingleberry.

That's like saying you have the biggest midget penis or something, c'mon man!  Yeah it's big, but you're a midget... no offense to midgets on this board.

I don't think you're at 300 just yet, but imagine what it would do with some honest intake flow right?  You keep underestimating the potential of this thing, and I'm not sure I understand why.  There's no reason whatsoever to not push 18 PSI at this thing with a better turbo, other than the aforementioned traction issues (trust me, I feel your pain there).  Put that new rear end together, and I'll see what I can do about the turbo.

I'll also bring you 3 more coils to mess with.

lol
I'm sure it can, in fact I know it can, but I'm also trying to keep things reliable and less broked (though I realize that running a T25 near it's efficiency limit isn't exactly good for the turbo, but who cares, it's a T25!), keep in mind that I have 10:1 CR cast pistons that aren't designed for boost too.
If I had another car, I wouldn't mind pushing it a lot harder. I gotta keep it within a comfort zone.

I know everything but the pistons can take 450BHP with out a problem, but I can't afford the cost/downtime of dropping in new pistons right now.

Though a T3/T4 hybrid would be a decent compromise I guess, though a big 16g would be nice and still keep an good spool.

I wish I had a good chunk of change to drop on a few good items for my S12, main thing would be a nice set of QA1 coilovers for the 240SX rear suspension, so I can get some of that done. Which reminds me, I gotta get some time on the lathe at work and finish the prop shaft adapter.

Stupid bills, oh well, after tax time we'll hopefully have some of that cleared out, and I'll have some spending money again.

You're not in any danger of a meltdown, trust me.  In fact, you're farther away than I am.  Let's look at the facts for a second.

I have an air-cooled 1.9 with cast pistons, 8 valves, NO intercooler, NO meth injection, and I push more boost than you do.  The one thing I do have, is 7.3:1 compression.

You have water cooling, 16 valves, a huge IC, meth injection, but a high compression ratio. The IC will take care of IAT's no problem, and the water will cool the combustion chambers so you're not in any danger of a meltdown.

Wild guess, you should be able to hit 18 PSI without breaking a (nervous) sweat on a regular basis.  You have more positive balls bouncing in your court than I do, and the VW is currently my only car too.

You don't give those parts enough credit.  It's more in the tune than anything else, anyway.  A CA18 with no turbo and a bad tune will melt down just as fast as an SR20 turbo with a bad tune will. Staying out of detonation is the most important thing, but keeping your AFR's in check goes hand in hand with that.  I know you already know this stuff, but I also know you run far too rich in an attempt to stay in that 'comfort zone'.  I guess what I'm getting at, is with the stuff you have, I'd be pushing that thing WAY harder than you do.

Pushing limits will have to wait for warmer weather anyway, so I'm not going to sweat it right now. Once we're into the part of the season where I feel safe to put my regular tires back on, I'll see what I can squeeze out of it. I'm fairly sure there's another 15WTq I could probably get in the peek power band with a little more timing.
I'll have to get the headphones out and listen for knock, though with the cold dry air right now will be way different than summer weather, so I'll have to make sure it's not too much when things are heat soaked.

AFRs are a lot better now with the MS though, it's a lot easier to get those where they need to be, compared to the stock ECU. Real time tuning is pretty nice, I wish I had a r/t board for the OE computer.
I did get them better on the stock setup (11.5:1), but I had some problems with warm-up enrichment and timing being pulled out.

I'm still getting use to tuning by VE, getting adjusted to how the VE bins progress as load/RPM increases. It was fairly linear on the OE setup, so I seem to be over estimating some of my guesses as to where some of the untuned bins should be. So I keep getting some rich misfires when I hit some load points that I haven't gone over yet.

AND I think cranking PWs are way too low for cold weather, it doesn't quite catch right and sputters until it get more fuel by the VE table. But I haven't had much time to play with it.

Oh, and what's up with your ASE settings, they're all 100%, shouldn't they be a percent lower than 100? The manual isn't exactly clear on how to set some of that stuff, or what exactly it does. I guess I'll just look at the source code and see.

Oh, and it won't be too much longer before my 450CC injectors are maxed, my last log showed 99% @ 7000RPM with a 9.8:1 AFR (one of those untuned guesses), so that'll come back into normal duty cycle once it's in a normal AFR.
It doesn't give me a whole lot of leeway with compressor flow though, so I might bump to 4BAR fuel pressure in the mean time (and get a little better fuel atomization too), but I'll probably get something in the 700CC range when I can.

Edit:
Do you have a spare Ben? If you do, I could weld that, then you won't have too much down time.
I wish I had a bigger TIG welder at home, then I wouldn't mind doing it here, but work is the only place I can do it.

OR, better yet, give me a core with the side bearing shims, and I'll trade you for my S13 welded diff.

11 is still easily a point too rich, so there's room for more power there- fuel is taking up space where there should be more boost!

The trick is to drive around with logging on and the wastegate disconnected, and let autotune do the work for you.  Once you have it mapped N/A, hook the 'gate back up and make manual educated guesses about what bin values will give you the AFR you're after.  I didn't use Autotune at all (it wasn't out when I did the conversion), but full manual tuning isn't all that hard.  I think it might have taken me a week to get a rough tune to where I could drive it to work, and within a month I had it fully mapped to 12 PSI.

One thing I noticed: the areas around idle tend to be a little busy, simply because it takes so many different combinations of fuel and spark to get it to run smoothly.  At WOT though, it's much easier to understand.  Bin numbers rise in value linearly at WOT (100 Kpa line and above), small to large, bottom to top.  They stay more or less the same as RPM rises towards redline, though I typically add a little fuel at the top end just to be safe.  This makes sense though: the engine doesn't use any more fuel the faster it spins, the only thing that causes a change in fuel consumption is a change in MAP.

Vertically, your bins should be bigger the higher up you go.  Horizontally, they should stay more or less the same all the way accross.  While you're at it, have a look at your logs and see what areas you tend to cruise in.  Program it lean in those areas (like 16~17:1 or more), then add a bunch of timing.  Your higher compression (and good head design)should make that thing very tolerant of lean mixtures, so it ought to be possible to return some good MPG numbers.

The last tune I loaded on the OE computer was right at 12:1 I think, but a few spots were probably too rich yet. I didn't spend a whole lot of time on it.

I had the N/A tune roughed out in a few hours of driving around, it wasn't too bad.
It's already running really well, it just needs a little more fine tuning in a few spots. Might have you ride along and run the laptop, see if maybe we could get it a little better.

I've been trying to keep it around the same area in cruise, like I had it on the old ECU, about 15.5-15.8:1. I have overrun set too, so I can just let off the gas and cut injectors too (I know you had that disabled).
I'll probably lean them out a little more, but the engine does seem to like running near stoich.
On the old setup, I was getting at least 26MPG, so if I'm getting about the same now, I'll know I'm close.

I did notice that fuel doesn't increase much as revs go up, unlike the OE computer which were fairly linear. That's probably what's throwing me off in my guesses. Just getting use to speed density I guess.

Ah.
Well, I was gonna say I might be able to do it with my Lincoln welder, helium does give a nice hot arc, but I think the tank is empty now.
90AMPs might be just enough too, at least with the 625 Inconel filler rods that I like to use on it, I bet I could get it. If I had some gas of course.

Some people say no higher than 100PSI at your max boost, but some injectors will actually fail at less than that. Personally I probably wouldn't let it get more than 5BAR (73.5PSI), which also happens to be the max my fuel pump is rated.

I was talking to David Deatsch of Deatschwerks a few weeks ago about the tolerances of the fuel systems for a wild idea I had.  He told me MOST fuel pumps and injectors will hold up and work just fine up to 100PSI.  He said that that is the max pressure they run all of their injectors up to when testing them.  He told me that if you want to go higher than 100PSI, then all you need to do really is get new fuel lines that can take the higher pressure and injectors with larger solenoids.

Lol yea original hoses got to go, dry rot is a nasty thing.

Factory pressure should be 44.1psi (3bar), that's with the vacuum hose disconnected.

Anyway, I've modded my cas trigger disc for cam sync, all I need to do is build the second trigger input circuit and wire up the output on the cas sensor.
Then hopefully I won't have any start-up/starter kickback problems anymore, and be able to run wastespark or coil-on-plug.

Correction - I forgot the 5v pull-up for the processor input, which was actually the 4.7k ohm orange lead, and the output to the processor was supposed to be via 1k ohm resistor.

Title: Matt's S12
Post by: seishuku on 08:45:38 PM / 03-Jan-10
Well NOW it starts with nearly a second on the starter!

Apparently stock Nissan ignitors need a fair amount of current to trigger, so I had to put in a 390ohm 5volt pull-up resistor to the ignitor trigger lead.

However without the pull-up in there, it was still able to run with a fixed duty cycle and the spark inverted, I figure it was still able to get JUST enough current through just the D14 LED (spark A output) and it's 330ohm resistor.

But anyway, with the proper pull-up installed, I now have proper dwell control and "this cylinder" timing mode works too.

For anyone interested, I have my trigger angle set to 80 degrees and the timing fine tuned by the normal means (rotating the distributor until it matches my fixed timing setting).

A little more fine tuning to the after start enrichment and warm up enrichment and it'll be running better than the OE ECU! Even from a dead cold start.

Now to get an ignitor that supports 4 coils (or a few more power transistors), and get coil-on-plug going. Or a 4 cylinder waste spark coil, doesn't really matter to me, either way will rid me of the distributor.

I'm thinking of switching to the hi-res code (tighter control of pulse width length), which also has some neat features that aren't in the current Extra firmware (029y4), like a real turbo anti-lag!
Not that I need that feature, nor a need to destroy my manifold/turbine/exhaust.  But it's neat to play with some.

I LOVE P&P!!!

When I lived in CA, that's where I got all my turbos from. 1/2 off day was the shiz, you just can't beat $30 for a turbo, and I took home plenty of them. The one here on 41 isn't all that great though, mostly late model domestics (so it's still good for EDIS parts, hint hint). I did get an IHI twin screw blower off a Mazda Milennia for $60, though some fartbag had already taken the twin air-to-water intercoolers before I got there.  

Gonna put that puppy on a 2,366cc Porsche engine, and see how long it takes the Rancho Pro Street transaxle in my Bug to break.

Since I've installed the MegaSquirt, I haven't had the VVT stuff connected on my SR, so I've been driving around with a in/ex cam overlap of 1 degree... Which apparently is good for turbo spool, though I don't see it, but it for sure does nothing for low end torque.

So I finally got around to reconnecting it, and WOW I forgot how much low torque my engine has.
It seems to get a faster spool too, despite what I've read.

Downside is that I need to spray a little more fuel while VVT is active (21 degrees overlap). Oh well!

Yea, it's not too bad when it's all cleaned up, but I still don't have a lot of traction.

Edit:
Also, winter is a good time for parts of the tuning, especially if it's a daily driver like mine. Cold starts are a pain to tune, and during the spring/summer time, you can't tune that stuff.

And with the cold air, you're less prone to knocking, so you don't need to be as careful when tuning either.

Since I just guessed at how much fuel the VVT was going to need, it wasn't really running very well this morning... So, I did a good retuning session tonight.
I had added too much fuel at the top and very bottom end, but the overall additional fuel needed is about 10% richer.
Pretty big difference if you ask me.

Other problem I'm having is this weird gravel-against-the-bottom-of-the-car noise at high speed (most of the time it sounds like it comes from the rear?), high load... I was hoping that all it was, but tonight I did an expairiment and dropped timing in boost by 5 degrees and it seems to have gone away.

So... Maybe it was detonation like I fear, or just coincidence? I guess time will tell, I'll have to do some WOT pulls under those conditions and see if it's still there. If it is, then it's just shit on the road getting kicked up.

I'm thinking it's probably just road debris, because I've shut the engine down while it was happening and the plugs are all clean, so I donno.

I gotta schedule a few hours on a dyno, so I can get the timing ACTUALLY dialed in. That's the only thing I can't do correctly.

Haha and im good at doing it by eyesight as we found out during our last meet   My VG was damn near dead on when we put the timing light to it.  I'm sure boost is a completely different ballgame than slightly adjusting for premi or lowgrade fuel on an NA though (considering it makes very very little difference on my NA )
Title: Matt's S12
Post by: seishuku on 10:28:46 PM / 27-Jan-10
 Yeah, NA is pretty loose on the timing, compared to when you're pressurizing things.
Case and point was my old CA20, I was able to run 30 degrees base timing, and only started to knock at around 38! On 93 octane of course.

I wonder if maybe the reason I was able to run the timing I was with out knocking on the old ECU, because of the timing pull issue I had with it. It was probably pulling out just enough (for whatever reason) to keep the pinging at bay.

*shrug* It pulls hard either way!

If I'm not mistaken, the way they find Octane ratings is different between the US and other countries.

I'd say his 93 octane is near the same as 91 octane at some other US gas stations, and that the 93 relates to the 98 you use there.  Various companies use different formulas to calculate the octane rating, so its hard to tell honestly.

Quote from wiki (so take it as you will):
Quote
Different countries have some variation in what RON (Research Octane Number) is standard for gasoline, or petrol. In the UK, ordinary regular unleaded petrol is 91 RON (not commonly available), premium unleaded petrol is always 95 RON, and super unleaded is usually 97-98 RON. However both Shell and BP produce fuel at 102 RON for cars with hi-performance engines, and the supermarket chain Tesco began in 2006 to sell super unleaded petrol rated at 99 RON. In the US, octane ratings in unleaded fuels can vary between 86-87 AKI (91-92 RON) for regular, through 89-90 AKI (94-95 RON) for mid-grade (European Premium), up to 90-94 AKI (95-99 RON) for premium (European Super).

I know that (R+M)/2. is what is listed on the pumps as the rating equation in the US, which would be AKI or Pump Octane Number.  I'm going to guess that in Aus and other areas, the RON is listed.

Yeah, our 93 is averaged RON/MON, so our 93 is basically your 98.
I'm running a water+alcohol spray too.

Which is also another reason I'm not sure if that was knocking or not, because with the water spray it should be next to impossible for it to detonate.

Have you figured out the dwell time of the coils yet, or are you just gonna pick something out of thin air? Probably would be a good idea to scope them, or you risk overheating the coil or burning up the drivers. I'm sure Tim would know how to do this, probably means measuring the rise time of the primary or something.

just to be sure I'm not nuts here

"Dwell is the amount of time the coil is allowed to charge before releasing the energy to the plug wires."

Is that correct then?

According to a link I found here (Haltech ECU's official site), it seems that stock SR20 Dwell Time is 1.9ms

Yes. If the coil is allowed to charge for too long, it could potentially draw too much current and burn itself out. Same goes for the drivers, having too much current running through them is a bad thing.
Title: Matt's S12
Post by: seishuku on 09:18:56 PM / 07-Feb-10
I'll probably start around 1.5 or 1ms, unless I can find that page with the actual values on it again. I seem to recall that they're around 1.5 though.

Here's launch control/flat shift part one:
(https://i.imgur.com/pteXrxN.jpg)

Got the proximity switch mounted to the clutch pedal box, so that the switch just turns on when the clutch is disengaged, but not to the floor on the starter interlock switch.
I just need to make up a circuit with either a transistor or just use a small relay to send the signal to the MegaSquirt (the switch outputs 12volts, or whatever the input voltage is).

Title: Matt's S12
Post by: seishuku on 05:48:50 PM / 09-Feb-10
Yea, as soon as I write my own program for it, the current "PocketTune" for MegaSquirt won't run on my smartphone for some reason (missing DLL or something), so I'll probably have to come up with something.

Dwell is a per-coil value, it depends completely on the coil.
You can run a little more dwell for a hotter spark in a boosted app, but it'll shorten the coil's life a lot.

Yea, but that's besides the point, the coils on a CA18DE and CA18DET both have the same dwell, but ones a turbo app and one isn't.
It's the coil that dictates the dwell, not the application.

I'm still thinking of using QA1 coilovers, that way I don't have to build a strut tower. Should make things a little easier.

Did you modify the subframe or the chassis? I think I will just change the mount points on the subframe, that way if I ever use it for racing that has a rule on chassis changes, it'll help stay clear of that. Hopefully.

Yea, pretty much. Though most of my current system will stay the way it is, since it's already to the rear. I just wanted some extra 3-bolt flanges.

I didn't make a turbo outlet flange though, but that's because I'm not really sure what T3 it will end up being, since there are a lot of different ones and they all seem to have different outlet flanges.

I'll probably make it with the T2 flange to start out with, then switch it up with the T3 later.

I need to decide if I want to make a top mount or bottom mount too.

 i modified both the subframe and the chassis... that chassis beam in the back that the rear mounts line up on..i removed it and welded in some square tubing to get a nice flat surface to work with and then i went to the subframe and modified the front mounts....extended them to the oem mounting point. the outer beams need to be massaged a little to clear the camber rod mount.. and i think the traction rod as well

Nah, the KA was in pieces and went to Jay.

It might have been knocking, but it's hard to say. The plug is fairly clean, the damage looks like it was beat up from the ground strap bouncing around.
Timing was clean and stable at a low value (lowered in-boost timing a few days ago) and AFRs were good too.

I think the strap did the damage, just broke off from fatigue. I don't know.

Sad to say, but I may end up having to part out the '12... We just can't afford to fix it.
I guess it depends on what broke.

Not yet, I will be tomorrow though.

Items on my buy list are as follows:
Head gasket
Piston
Rings
4 60CC/min spray nozzles (going direct port on the water injection)

IF things are the way I think at least.

I am thinking of going with some CP or Mahle 9:1 forged slugs though, new rings and bearings.
It depends on how fast I need to get things done, otherwise I'm gonna take my time and build it up.

I am going to take advantage of the situation though, and get some work done that I can't do while having to DD the car.

Bummer!!!!  

Told you I heard something funky last time I was up there...



It doesn't look like detonation to me, there's no evidence of melted metal or metal transfer. If you had detonation there would be flecks of aluminum on the plug from the piston melting, or globules of what was left of the plug. It looks to me like the ground strap broke off, but now you're left with a 'chicken vs egg' situation: Did the ground strap get hit with a chunk of piston, or did it break off of it's own accord and do further damage? One thing's for certain: You'll need parts.

Well from what I can gather, it may have been a chain of events. I think the water injection might have failed to get enough spray to #1 (the reason I want to do direct port injection), which might have caused minor detonation (non-audible) which then might have caused plug failure and upset the combustion enough to detonate harder and crack the upper land.

But I have a hard time believing that it was knocking at all, like my brother said, there's no aluminum transfer on the plug, no pitting on the piston, no pitting of the upper cylinder. Now, I haven't looked at the head yet (I didn't want to pull the rockers and shims right now), but I'm willing to bet that it looks just like the piston crown, nice and clean.

Which brings me to this:
Less water injection flow to #1, meaning faster burning flame front (harder combustion).
+4 years running.
+10:1 compression N/A cast pistons.
= Cracked ring-land due to mechanical stress.

The real shame is that this happened before I could get it on a dyno and see what kind of power I was producing.

I'm about 99% sure that will hone out though, it's pretty minor, just rubbing damage. It didn't score the walls at all.

Doesn't really matter, as long as it drives and won't break down.
We don't have 200 cash right now though, still trying to figure out exactly what we're gonna do.

I got the piston out:

Top ring was stuck, either welded in or just the aluminum getting rolled over from the side damage.
There is very little pitting at the upper ring gap (where it was stuck), but I still don't think it was detonation.

It's not cracked anywhere though, if it weren't for the skirt damage, I'd reuse it!

Why is it that the cheapest forged pistons that I can find are all 86.5MM?

DOES NO ONE MAKE STANDARD BORE FORGED PISTONS?! Ugh.

/rant

That being said, I might just get 8.5:1 OEM cast pistons.

With the 8.5:1 CR pistons, I can use a 1.1MM head gasket and still hold at least 9:1. Not a total loss, though it would be awesome to have 9.5:1 forged slugs, but I don't want to bore .020 over and cost and arm and a leg.

I'm going to hone it myself, if the wear marks don't come out, then I'll send it out.
The goal is to keep cost down, and I don't plan on replacing any bearings (since they're basically brand new looking), otherwise I would strip the block down too.

I don't think it was detonation either, but just because you don't see the typical tell-tale signs does not mean it was not occurring...

This is all per my experience, yours may differ.

There are a few different failure modes detonation can manifest itself in, the most common one I'm sure you're all very familiar with already: rattle can noise under heavy load, melting aluminum, wasted plug electrodes, holed pistons, ect. That type of damage is caused by heavy detonation, which occurs over a long period of time at heavy load. By long period I mean going up a long hill at full throttle, not an actual time period like a month or something. The engine is under heavy load, at less than ideal conditions. The condition may be less than required fuel octane, overadvanced spark timing, overly lean fueling conditions, or even an overheating cylinder head that goes unnoticed (trust me it happens, and a head that would have been reuseable gets destroyed by detonation instead of just being warped). Detonation consistantly occurs, temps in the combustion chamber hit Chernobyl-like levels, and next thing you know your pistons have skylights. I've even seen it so bad that the pistons actually survived, yet the head melted down so bad the seats fell right out of the casting. That was a Cosworth YB engine, back when I lived in Sicily.


It's the other modes of failure people seldom identify, because they are so easy to mistake as another issue. Things like wiped out rod bearings (usually only the upper shell) for no apparent reason which get written off as a bad oil pump or oil starvation, sunken valve seats/melted valves, or in this case you might suspect detonation because of the locked rings (though I doubt that's the case here). This mode is consistant with detonation that is still quite intense, though it happens more or less 'infrequently'. In other words it doesn't happen enough to melt anything, yet it's still there giving your bearings and piston crowns a literal hammering. The force of the colliding waves of pressure inside the combustion chamber can be so great that the piston crown actually droops down over time, causing the rings to become frozen in their respective lands. I saw this exact thing happen to an N/A VW engine, which had an intake leak that caused one cylinder to run lean.

If one single detonation event is extreme enough, it can cause enough pressure to pop the head gasket in one fell swoop, but the gasket itself is not at fault- it's the head studs allowing the head to lift off the block. Surely this one is rare, though it does happen, usually in high-HP race engines or cases where the studs were inferior.


I don't think anything really went wrong here. I think it's a simple case of material fatigue caused by parts that weren't necessarily inferior, just not up to the task of running in a high CR boosted engine. Forged slugs would not have failed in this manner, so I highly suggest you seek out a set even if you have to put off building the engine for longer than you'd like. I already made my donation to your effort, so unless you can use VW pistons...
Title: Matt's S12
Post by: seishuku on 04:09:25 PM / 26-Mar-10
Yeah, it's looking more and more like just material failure.

I got a bookmark for some Wiseco 8.5:1 forged slugs, set of 4 with rings for $450. Going with that is a Cosworth 1.1MM head gasket.
I'm debating whether or not to get head studs or not, head lifting isn't a real common problem with SRs, but I will be replacing rod bolts... Those have been known to fail when reused.
We'll see I guess.

In the mean time, I've been cleaning up stuff that I've been wanting to do for years.
Resurfaced the flywheel at work, since I have a spare clutch disc that will be going in when it all gets reassembled.

And actually, now that I think about it... This is the very reason that the OEM turbo SR has piston oil jets, they keep the cast piston cool and the rings from seizing.

Yeah, forged is the way to go when running with out oil jets.

Well the forged alloy doesn't shrink and expand or sag like the plain cast material, so theoretically it shouldn't ever happen.
I mean anything is possible and it wouldn't be a bad idea, but it does mean I have to completely strip down the block, drill and tap the bosses, source the jets... And I'd have to make sure I got every last little bit of aluminum out of the oil channels too.

I was hoping to just hone the short block and slap in the new forged slugs, and reassemble. Keeping it simple.
If I have to send it out and have it bored, then I probably will.

But like I said, the only reason Nissan put those jets there are because of the cast pistons. The NA motor doesn't have them, because let's face it, it just doesn't put down that much power.
Even though the KA has them, but partly due to US emissions, they burn rather hot and I guess they felt that the KA needed them.

man youve really got that thing gutted!

ic on the squirters, didnt know you had to drill the oil passages etc.

realize with any replacement pistons a bore to match is standard, probably why you're not finding any in OEM sizes.  Forgies expand more during warmup, so the bore needs to account for this, and everything better be clean and straight otherwise youll damage the new pistons.  I think its worth it for you, just more saving will have to go on first lol

I can do that, I gotta let the paint dry on the main tube first though.

The key part here is this:
(https://i.imgur.com/I9XTck4.jpg)

Welding of the spool valve torsion component, only needs to hold it, so no monster weld needed (it's already strong enough to take steering stress). I used a nickle filler rod, so I can get good strength with little heat input.

Otherwise, removing of all fluid lines, internal fluid seals, anything that might cause friction internally. You still need the external seals, since you don't want dirt getting in.

I pulled the bell housing off my trans today, to inspect where that whining is coming from... So far I haven't found anything for sure, though the counter shaft front bearing does have a little slop in it.

The gears do have wear, but it does have 160000+ miles on it, so that's not too surprising.

Not really a good way to show the play in the bearing, but here's a video:

The bearing shouldn't have any play like that, and only the two front bearings do that. Though the main shaft bearing isn't quite as bad.

It still rolls really nice, but it shouldn't be that sloppy.

Well all your gear clusters are scuffed on the toes, that can cause a whine.  Bearings will typically make a rumble or lower frequency sound.

160K is nothing for a trany, however, improper servicing will shorten the life considerably.  That scuffing could easily be from too long a gap between servicing.

That stamped steal piece in the foreground of the above shot needs to be standing up straight, it plays a vital role on moving lubricants around.  Also, make sure it is  oriented properly.  Check the FSM.

Do you have pictures of the "odd metal chips"?  Are they Chunks, Chips, Flakes, or?  Can you see where they may have originated from?  Chunks are bad, chips and flakes are not as bad...

As far as I know, the trans was serviced regularly, I know I changed the oil on a regular basis.

I'm pretty sure I knocked the oil gutter over then I was disassembling.

I don't have pics of the metal pieces, they were more flake like than chunks though. No clue where they came from.

Some wiring changes too:

From this:

To this (though a little more simplified than the other):
(https://i.imgur.com/BjefO40.png)

Pretty much, if the low or high beams are on, the lights are up, if they're not, then it's down. Simple.
I don't care for the retractor switch (if I want to clean them, I'll just turn the lights on!), and what's the point of them staying up with the parking lights on (until you switch everything off)?

Also, right when you turn the lights on, they're on, it won't wait until the lights are fully up (that's what the pair of headlight relays are for). But it reduces the number of relays until the hood from 7 to 3. I like that.

Cosworth makes good parts, I can vouch for that. When I lived in Sicily, my roomate and I each had a Ford Sierra Cosworth (16v turbo). We beat the living sh!t out of those cars, no mercy whatsoever. Mahle made the pistons in those YB motors, so you know it was some good stuff. Never blew anything up, and they were a lot of fun while we had them. Mine was a green top, his was red. Wish now that I'd had a blue top AWD Escort, that's straight road rally domination right there.

As an aside, I dyno'd my VW Beetle recently in Indy. It's putting 150 TQ an 120 HP to the wheels, which isn't bad at all for an air cooled non-intercooled 1.9L engine. I figure I should be into the 200 range once I get the meth spray installed and turn up the pressure... That's deep into the 12's in the quarter for a car that weighs 1800 lbs. Wish me luck, Union Grove Raceway is open!!!

Ha... Our tax return was gone back in February.  Stupid bills.

But yea, the Escort RS and Merkur XR4TI (though not the same engine as the Sierra Cosworth, but still impressive) are still my favorite cars of all time. Simply bad ass.

If the pinch come down to it, I might try picking up a flat top Sentra SR piston and see if it's the same (if I can find a 65J cast flat), otherwise I found an awesome deal on SR20DET cast pistons.
I could get the engine back together for like $300, but it would just be 8.5:1 cast pistons.
Though if I could find a 65J 10:1 piston, I could pick up a chromolly ring set (to help avoid this problem in the future, though wall damage increases), hone everything and probably have everything up for around $200.

At any rate, it's going to be awhile.
And I *may* have to find another transmission, this one is starting to scare me.

I'll put up some pics why it scares me later.

Oh, and yeah, it's the appliance stuff, it's only a $1 more than the normal enamel, so I figured why not.
It covers better than the Rustolum ultra coverage too.
Neatness doesn't count on the bay though, it's going on heavy for max protection, both in the bay and in the wheel wells.

Oh, and Sterling, everything is still pretty damn clean and rust free, other than a few small areas with surface rust (like the lower front fender, near the door). It actually surprises me that it's stayed as clean as it has, even after being driven every winter for 4 years now.

OK, now that I know what all this bullshit is about, I have made the executive decision to allow Wolf to put back his signature content.

I've also posted this:

http://club-s12.org/v3/index.php?topic=29840 (http://club-s12.org/v3/index.php?topic=29840)

If anyone has a problem with that, PM me. Or take a flying fucking leap. Whichever you prefer.

And now this thread can go back to the discussion of Matt's S12, and what he's gonna do with his engine situation. As Sam put it best, any political discussions belong in "Coffee Shop", and under the rules regarding civil posting.

And remember, this stuff is in my signature as the first image. FOR A REASON, sheesh.

Finished bay, just gotta reassemble the various parts then wait for the engine to go back in.

Bare engine block, waiting to be honed to spec for it's new forged slugs. Just the block and crank.

Here's some pics of the trans, on closer inspection there were a few chips out of the edge on the drive gear (4th):
(https://i.imgur.com/gaDNLsm.jpg)
It doesn't look that bad now, because I polished it up some, hopefully that will keep it from cracking the gear in half later on, at least until I can get a new one.

While I was in there, I cleaned up the reverse idler gear (the gear that you engage with when you put it in reverse), it was pretty chewed up, so I deburred it and polished it.

"Messy garage."

At least you can get your "wheels" into yours.

"Here's some pics of the trans, on closer inspection there were a few chips out of the edge on the drive gear (4th)"

Yeah forth may make some noise fer ya... of course these trannies are much looser tolerance than what I worked on, so the noise may not be so bad.

"While I was in there, I cleaned up the reverse idler gear (the gear that you engage with when you put it in reverse), it was pretty chewed up, so I deburred it and polished it."

Dude, that reverse cluster is done, it may work for a while but I would bet it will be sketchy getting in at times, if not always.

Not trying to piss on your parade, you are doing a great deal of work and learning plenty too. Bravo Zulu for the effort, takes commitment.

Time to go to the JY and start pullin Z trannies, for the internals, lotsa good mix and match stuff. only thing not usable is the tail cone, shift linkages and the output shaft.  Grab yourself at least three different 71-C's Look for the bands on the input shaft, they indicate the ratios inside.

Stay away for the T-5's, nothing usable there.

I wait till the local Pick-n-Pull has a sale and grab 71-C's for half price.

Peace, Wolf

Nah, it still engages the normal half gear when in reverse. It was already hard to get in some times, so no loss there.
I'm not going to go around beating on it in reverse anyway, it's not meant to take a big load.

I'm good for any Saturday or Sunday in May, as far as I know I don't have anything going on, but maybe labor day week end?
I'll probably have that Friday off, so we could do that Saturday maybe. I donno, I'm always open to suggestions.

Hell yeah, that's why I love the S12. It's light, looks like a piece of shit beater, and no one ever suspects it!
Gotta love an underdog.

Last time I was at Byron I pulled a 14 flat with a shitty RT and 60', I know I would have been in the deep 13's, if not real high 12's (if I can hook).

Hm... I'll let you know, it all depends on measurements from the bores and pistons.

Thanks guys

Ok, some more work on the engine... I pulled the mains and looked over the bearings, they all look in ok shape (about normal for ~80k miles).
My problem is the bearing grading though, according to the block (23333) and the crank (01111), I would need one STD2 and 4 STD4 bearings... However, all the bearings I pulled out are STD0.

What's the deal with that? I know they're all original from the factory parts, the engine has never been opened until now.

EDIT:
Ah, nevermind! The part number on the bearing apparently doesn't carry the grading, and I did manage to uncover the bearing color mark on one of them, and it does indicate a #4 grade (it's from the #2 main).
So that makes me feel a little better.

But the question now is, do I use Nissan bearings, or go with an aftermarket "standard" bearing set?
I'm thinking OEM.

I would go with OEM if you can afford the bread.  I used OEM on my VG and it gives me just a little bit less concern...    

Title: Matt's S12
Post by: seishuku on 03:53:00 PM / 03-May-10
I'm thinking that's the way to go, since the standard aftermarket bearings usually only cover grades 0 to 3.
That would be on the looser side of the oil clearances, and if anything, I want to tighten things up a bit.

I guess the right thing to do would be measure the clearances now, see where they are. I'll have to see what the plastigauge I have covers, I think it's the right range for the SR.
Title: Matt's S12
Post by: 200sxkitcar on 10:56:55 PM / 08-May-10
I would plastigage and go oem from there to get the closest to tolerances...

let Justin know if you need OEM bearings, he'll hook you up with a real good price.

Waiting for prothane bushings, they'll be here tuesday, then I can get the rear suspension back together and have it rolling again.

I wish I could, but I like living in a house!

Anyway, Prothane RCA bushings came in, look good... But I thought they came with new inner sleeves and only reused the old outer?

Not that it's a big deal, two were trash anyway (seized bolts)... So I guess I'll look at work, see if we have any scrap structural tube or solid stock that I can drill out that's close enough.
Title: Matt's S12
Post by: seishuku on 03:12:57 PM / 27-Jun-10
Progress!

I have the solid subframe and driver side control arm back in!

The solid frame really stiffens up things in the rear, it'll be interesting to see how it and the prothane bushings change how the suspension reacts.
Some stiffer springs would be nice too, but I just gotta get the car back together and running again.

Only thing though, is apparently the subframe mounts on the chassis were just a little bit wider than the subframe... Not sure what's going on there, BUT a little work with the jack and a little tapping with a 3LBS hammer got things into place.
I could probably jack the rear up by the subframe now... Without the diff bolted in!
Title: Matt's S12
Post by: seishuku on 07:37:15 PM / 28-Jun-10
Back on all fours!
 But it does roll again!

Now, to get the engine together.

Edit:
Oh, and how solid everything is: If I tap on the subframe or differential, it sounds like I'm tapping on the chassis!
It'll be somewhat noisy... Oh well.

Post by: seishuku on 09:04:59 PM / 29-Jun-10
Sorry man, the old one got hacked up to save the control arms.
It was bad anyway, one of the bolts was seized to the frame and tore while trying to break it free.

I suppose it could have been saved, welded back up, but I already chucked in the scrap bin.

Edit:
I can always make another one though, it's really easy to do. Just need four 1.25" USS plain finish flat washers, and the original inner sleeves from the bushings.

haha its all good, I was hoping for a blank subframe to sand down and clean up and paint and all that, more so than the solid thing

I've got my MSA bushings to put on my car someday, I just dont feel comfortable doing it myself.

Question is....  How out of round are the holes? and there are still heavy scratches visible in the one image. those will leak.  If those two are the only bores with damage, just have them sleeved, prolly still cheaper than a re-bore, once you factor in the new hardware and all.
Title: Matt's S12
Post by: seishuku on 11:58:17 AM / 03-Jul-10
Why would I sleeve them? I can safely bore it out to 88MM, and even .5MM over would have more than cleaned it up, but why would I do that when obviously honing it (which needed to be done before rering anyway) cleaned it up.

Yes, there is still a very faint line visible, and I'll probably go back over it again because I'm picky. The camera flash makes everything look way worse.

It's just cylinder one, two different views.

Also, at only 65k miles, it's not going to be out of round, even though it's low miles, I did already check with an inside mic, and all is well within spec.

It's only rubbing damage, it didn't chew up anything. Aluminum is softer than steel ya know.
Title: Matt's S12
Post by: Wolf Dilworth on 11:42:32 PM / 03-Jul-10
Your right, damage looks worse, if you checked it with a mic then that is fine.

You did not put that little detail in. There can be tons of damage from softer metals.  You clearly have scratches from the old broken rings. Those scratches are going to have an affect on the end result.  I put a scratch in one of my cylinders during rebuild, I took it all apart and had that cylinder sleeved because I do not plan to open my motor for several years.  YMMV.  I do not like to build motors half ass'd, honing to repair cylinder scratches is just that in my book.  Just my opinion.

Good luck. Like the thread.

Found a good deal on pistons, rings, and bearings on ebay for less than $150, so I ordered that.
Hopefully I'll have a short block put together soon, then I gotta get the head gasket ($30 shipped) and a few minor misc items (a few o-rings, from main seal, and a clutch slave).

It'll be a little lower compression before, since it was either 4 new Sentra 9.5:1 pistons or one new 10:1 piston, so I opted for the lower CR (plus it was a nice package deal). It'll make me a little less nervous while working on the tune.

Then I can start saving for forged parts and then really start kicking things up.

Hey Matt,

I have money for parts but no time to do the work, you have no money but you do have spare time. Wanna trade? I got a Mini Cooper that needs the floor welded back in.

Yea, I wouldn't mind working on the Mini in my spare time, after I get my car moving again of course.

Well, I got just about everything I can do, until the head gasket comes in tomorrow.

How 'bout helping me install my meth injection kit, so we can have a little showdown at high noon?  

Be interesting to see which car is faster: an S12, or a VW Beetle at 18 PSI?


EDIT: don't forget you need to reseat the rings now, so no synthetic oil for the first 1000 or so miles...

She's back on the road!
Gotta retune a little because of the compression change.

Now, the question is, do I break in on boost and drive normally, or keep it NA?
It's awfully loud with the wastegate open, but it is drivable.
Title: Matt's S12
Post by: Big Brother on 08:28:30 PM / 28-Jul-10
Drive it like you stole it, the rings in my engine didn't seat until I did just that. My personal feeling is that if it's gonna break, it will do so in the first 100 miles regardless of how it's driven. So unless you doubt your rebuild skills, go ahead and flog it.

That's pretty much how I was planning on doing it, hard and fast. No one else ever seems to think it's a good idea though.

On first engine up to temp. Take it out for a steady 15 minutes of the hardest beating you will ever put it through. Hard acceleration, and even more crucially, hard engine braking. bring home, cool down. change oil and filter, check head bolts. good to go

Never let me down

Oh, also I made this:

12+1 CAS trigger disc, made it on our brand-new Mitsubishi WaterJet we have at work now!
Title: Matt's S12
Post by: seishuku on 06:14:28 PM / 01-Aug-10
I guess I got the D shaft key at the wrong location, I had to remove that so I could rotate the disc around to the right position.
I also had to drill out the trigger holes slightly, because it would seem that the water jet doesn't make a perfectly round hole, and the pierce points were screwing up my trigger events. Careful tooling setup would fix that, or use slots instead.
It's also too thick, and that causes other issues.

Anywho, it seems that the disc is working well now, and I'll cut a correct one later.

Apparently I also missed a ground on the engine, which was also equally annoying.
Title: Matt's S12
Post by: seishuku on 08:44:32 PM / 02-Aug-10
Got a few gallons of gas today, and did some driving.
Ran a few logs through the analyzer and now my VE table is looking pretty damn good.

I might do a little more tomorrow, see if I can get it a little better.
I also need to readjust my AFR correction table, I thought I get the upper RPM/boost areas to 11.5-11.8:1, but it's still at like 12.5-12.8:1. Weird, but whatever.

Also, somehow, one of my headlight bulbs got smashed... Inside the headlight housing! That's really weird, it's like it exploded!

SO WOULD EDIS!!!!!!  

I guess that would explain why the timing went down when it was supposed to be a fixed value in MT, huh? That'll teach you to mess with distributors... HINT HINT!!!!  

Strange about the light, was it one of your HID lamps?
Title: Matt's S12
Post by: seishuku on 08:56:01 PM / 04-Aug-10
I don't think I'll use EDIS, but I may end up putting a 36-1 wheel on the crank, and let that trigger MS. That would at leave be accurate at the crank.
Of course that would limit me to waste spark only, so no full sequential COP, but whatever.

No, it wasn't an HID, I have those on the AUX lights. It's just one of the cheap-o halogen H4's that came with the housing.

Made a Nissan logo out of some scrap plastic:

CAS trigger disc #4, for some reason I keep screwing up the trigger angle and MegaSquirt didn't like any of the others. This one SHOULD work:

AAAAAND, the beginning to my oil block adapter plate:

Still needs a little (a lot) of machining.
Title: Matt's S12
Post by: seishuku on 08:26:56 PM / 05-Aug-10
Yay, the CAS disc works!

It would seem that the lower the resolution disc, the more the timing will want to drift retarded. With this 24 window disc, the timing does still drift about .5 degrees, but not nearly as much as that last attempt (which drifted almost 5 degrees!)

It might have something to do with the way megasquirt calculates the timing and trigger events, which yea, I know wouldn't happen with EDIS since it does the timing.

It's not bad at only 7PSI, but it needs more timing under boost, below 4000RPM.

I gotta get the water injection back on, then jack it up to 14PSI.

A little side project:
Building a car PC?

Here's the motherboard tray, motherboard and hard drive. Everything is in their approximate location where they will be in the case:

Now if only I had enough material left to make it out of stainless... Oh well, painted steel will be fine.

It's only a 2.8GHz P4 with 1GB RAM and a 8GB HDD, nothing fancy. Will either be running WinXP Embedded or Linux.
I'll most likely be using something like this for the PSU:

It's actually a little smaller than I thought it would be, and might actually fit under the passenger seat.

I know one thing though, if I EVER make another one, it's gonna be out of stainless. Welding this cheap ass sheet metal sucks, I got a few spots that had quite a bit of porosity and a lot of burnback (though that might be because it's so thin).

I *SUPPOSE* you can have one of my Rad Shack adaptors, I'll try to remember to bring it next time we stop in Belwah. Hey here's an idea! I'll also give you a fuel injection computer, wideband sensor and intercooler too! Wait- I ALREADY HAVE!!!  Guess you can pay me back by finishing the floor in my Cooper.  

As for the supply for your onboard 'puter: why don't you just cascade a bunch of 7805's/7812's, and run it right from the car's electrical system? I suppose noise and ground loops would be the issue there, but you can always get a cheap inverter...

EDIT: I also just remembered that I have an HP netbook that crapped it's wifi ability the other day, it would be perfect for tuning. I'll bring that too.

Well gee, you didn't HAVE to give them to me... Coulda said no... I do appreciate it though, ya know.

And yea, the auto electrical system is pretty noisy, but I'm pretty sure I'd need something better than a few linear regulators, I figure I need at least 90w minimum.

I wonder if a standard ATX PSU could be modded to remove the 120volt part of it, and replace it with something like what a DC-DC converter would have. I would think the PWM switching would work just the same as long as the transformers are getting the right feed (1000 volts, or something like that? I don't remember).

Oh, also if any other MegaSquirters are interested, I can make more of those 24+1 trigger wheels real easy. They don't take long to cut, and can be made from cheap material. (I used some thin brass shim stock, because that's all we had )

I'm not sure about making those SR oil block adapters though, at least not out of the 1.25" aluminum. Takes way too long to cut (45 minutes) and I just don't have the time to do the finish mill work on it.

Since I can do some more tuning again (thanks bro!), I worked on the timing map some.
Nick, you should like it a lot better than what I had, it does make a lot more power off boost.

I based it off Ben Fenner's VEMS SR20DE dyno tuned map, tweaked it here and there, since we have the same CR it's a good base, but minor differences because I have the intake cam phasing.
He says it made 150WHP, so I'm probably a little higher (NA) because of the cam timing.

No worries, I think I'll do just fine without that cable. I have the wideband patched into my MS box now anyway, so I doubt I'll need to talk to the ECU and WB at the same time in the near future. Autotune and closed loop EGO correction FTW!

No worries, I think I'll do just fine without that cable. I have the wideband patched into my MS box now anyway, so I doubt I'll need to talk to the ECU and WB at the same time in the near future. Autotune and closed loop EGO correction FTW!

Here's an idea- stop procrastinating about how you always have ignition trouble and a small ass turbo, get off your duff and go buy the damn EDIS kit and a T3/T4 and beat off in your car because of how happy you are.

Got some new stopping power, not big brakes though (I wish!)

Bought some Bendix CQ ceramic pads, $50 for front and rear from RockAuto.
Stops much better than the old pads (super cheap Wearever I think), though I've discovered that there was still some air in my lines as the ceramic pads heated up the fluid and expanded an air bubble. :lol:
Minor issue.
The other issue I found, I need to rebuild the front calipers, piston seals are weeping and I have a torn dust boot. Normal for 20+ year old calipers.

It's hard finding decent front pads for the XE S12, as they got the smaller front calipers (rears are the same on all S12's, JDM, euro, US, etc), but apparently the 80's Maxima got the same front calipers and no one bothered to cross reference it to the S12 for some reason.

Anyway, they're a good mid point until I can get bigger calipers for the car.

Hm, it's possible. Though the 280 does have a slightly different ear shape on the pad, but it may very well work.

Seems my SR makes the most power at 11:1 AFR, that seems pretty rich to me... I wonder if my O2 cal is off, or the curve is off in MegaSquirt (it's set to LC-1, which is my O2).

Neat thing about MegaSquirt, since it's a speed density fuel system, you can kinda see where peak torque is made, which on my SR is right around 5500RPM and that's right where my highest VE bin is on MegaSquirt.

I gotta get this thing on a dyno, I really want to know what kind of power I'm making, and where I could tweak it to get a little more out of it.

Well, the inevitable happened... My modified original (25 year old!) CA20E starter no longer correctly starts my SR.
It'll catch sometimes, but just enough to get some squirts out of the injectors and nearly flood it trying over and over.

It sounds like the bendix pops up, but the ratchet part is slipping or the gear isn't engaging (motor keeps spinning, but not cranking the engine).

So, I had to do what I didn't want to do, and that's cut the pinion support off my SR's original automatic trans starter (manual starters don't have it, and are internally supported).
It's working so far, but it'll eventually break too.
Title: Re: Matt's S12
Post by: Arro on 05:18:17 PM / 19-Oct-10

Title: Re: Matt's S12
Post by: seishuku on 05:28:40 PM / 19-Oct-10
Donno, the planet gear support plate inside the starter is fairly thick, but it's also just cast aluminum, but I think if I can keep the crank priod short, it'll last long enough until I have money to buy a proper starter.
In the mean time, I think I can fix the CA starter. It involves some cutting and welding though and I would have to do it at work (haven't found the time yet).
So yeah, I could get another CA starter, but if I'm going to get a new one, I'm probably going to get one of those ISIS SR starters ($150).

You're up against 170+ in my 2500 lb Beetle, and that's before water injection and 18 PSI... It dyno'd at 150 to the wheels sucking in 250 degree air, I know it's more now that the CAI is installed. Time to play catch up! hehe

Well the 100% stock S13 SR20DET runs 205BHP at 7PSI, so given the higher compression and almost double the boost, not to mention the optimal timing compared to stock... It *should* be near 280BHP, though some days it feel like it's over 300. :lol:

Holy mother!!! that is FUCKING lean for WOT!!!

Also your duty cycle is at 85 while your AFR is over the top at 15+.... your duty cycle seems to hit a wall past at around 423s and levels out and even drops down as the rpm gets higher and the tps and manifold pressure are still maxed out... that is where the AFR gets wild... check your fuel map and enrich the bitch up

The weird thing is though, it wasn't like that on any other data logs, so I don't know what's going on all the sudden.
Unless I never hit those conditions or something else was covering it up, but everything else is consistent.

I gotta do another WOT pull and see what it's doing now, but it should be a lot better now.

Post Merge: [time]04:00:17 AM / 18-Nov-10 [/time]
Heh, running a few numbers show that I may very well be maxing them out.
On the bight side, if that's true, I'm making a tad over 300BHP. On the other hand, that means I need to either drop boost, up fuel pressure, or get new injectors.

I probably will just up fuel pressure, 4 bar will get me about 520CC/min and a little more breathing room.

I guess I'll put some 800CC injectors on my xmas/tax return wish list.

Post by: tommy on 09:43:39 AM / 18-Nov-10
Plugs look fine to me... that is weird taking into considaration afr 15+.... but then, you are probably not running WOT at more that 6000rpm all day long ;)

Cheapest way is indeed to up the fuel pressure... check if your FPR is still doing it's job, maybe you tuned it with a certain FPR at that given manifold pressure, but now the diaphragm is getting lazy and not oppening the way it was when it was newer (less old :P)...
Title: Re: Matt's S12
Post by: seishuku on 03:51:07 PM / 18-Nov-10
Heh, well that's just it, I may very well have been driving it like that for the past few weeks and I'm just now noticing it. Or maybe it's just that I haven't taken it that high up in the rev range to really notice lately.
Of course I don't take it that high usually, it only makes torque until around 5500RPM then levels off (stock cams), but I do like having the full range correctly tuned in.

And actually the FPR is a newer one off a KA I had in pieces, because the original SR one rusted out and was giving me trouble a few years ago... So I'm fairly sure that it's working correctly. (plus I'm lazy and don't feel like rigging up a pressure gauge again :lol:)

It is time to get an adjustable FPR though, I've been wanting to run 4bar anyway for better atomization to help smooth out the idle (which because of Megasquirt's batch fire, isn't as smooth as the OEM sequential system).

Just remember: to get an accurate reading from the plugs, you must make a WOT run, shut the engine down as soon as you lift your foot, then pull them out. If the engine runs for any period of time thereafter, the readings are bunk and meaningless because the reading you are looking for will be 'covered up' by other operating conditions. It's entirely possibly to have massive detonation and completely miss it, because the aluminum flakes will get covered up by carbon very quickly. Also, a lot of the time you have to look at the plugs with a magnifying glass or very high resolution camera- the metal flecks left on the ceramic insulator are very small. If you're going to read plugs, I suggest you buy several pairs and cut them open after runs to analyze them completely. There's a tool to cut the treads off, it can be sourced through many speed shops or online.

As far as the AFR reading: your wideband mayby taking a sh!t. I've heard from more than a few people that the one you're using will give funky readings right before it buys the farm. Borrow my WB and bounce those readings off what you've already observed just to make sure before you assume something's gone horribly wrong.

One last thing: at 85% DC, the injectors are past the safe margin already. You need larger injectors... AND A BIGGER TURBO!!!!
Title: Re: Matt's S12
Post by: seishuku on 10:53:11 PM / 18-Nov-10
I'm not worried about damaging anything at this point, it was 15:1 for very brief time, which yea could blow a hole in the piston, but with as cold as the air charge is and with the timing it's not likely to do anything.

I donno about the wideband, I suppose we could check it with your equipment and see how they match up. But everything in the VE table that hasn't changed is still reading the same AFR, so I'm willing to bet that it's reading correctly.

Yea, 80% is my usual safe zone, but at this point I would rather have a 100% DC and at least a 12.8:1 AFR instead of 15:1. Ya?

Anyway, next on the table is an adjustable regulator and bump it to 4bar, that should bring my DC down to near 85 or 90 and have a better AFR.

Well it's installed, I ended up just tapping the FPR port for 1/4" NPT.
The gauge on it ruptured though after a little bit, so I just pulled that off and plugged the port. It was a crappy non-liquid filled gauge anyway, wasn't really designed for this application, so no big loss.

ANYWAY, at 60PSI (a little over 4bar) it feels MUCH better, power is a lot smoother and pulls no problem at the top end.

Bah, you could lose 2 whole points of AFR and still be very safe. Even after you pull fuel out though, I suspect you'll still be near 80% DC. That means you still need bigger injectors, so bust out the plastic card girlie man.

No, that just means I'm at the injectors limits, and will eventually need bigger injectors. :P
That can wait until I get a bigger turbo, it's pointless to even think about more power when it's winter out.

Either way, it's still fairly impressive for just a little T25.
The record for a T25G is like 278WHP (on a SR) I think, so I may very well be close or past that. At this point, I think it's dyno time.

No, it was originally a DOHC motor that was in front of that trans. The idiot just had a spare truck single slammer block laying around, and did that one

I missed what is wrong with your tranny apart from being blown.... because if your gears are all fucked up but the shaft are in good condition, you could use your original case and shaft (imput/output/counter) and just swap all the gearset/syncros/bearing over to your old tranny's shaft inside your old tranny case... it would take some time, but you won't have to source a driveshaft and cut your transtunnel...

3rd gear is missing a chunk.

I thought about using my s12 main shaft and the S13 gears, but it's a pain in the ass to pull all the gears off and then press them all back on.
It's just easier to find a front drive shaft section, plus then I could later on just drop in another S13 trans if I have to (instead of trying to find an S12 trans).

Bolt-in rear chassis bracing ideas
(https://i.imgur.com/2EnhEly.jpg)
(https://i.imgur.com/q5Df8it.jpg)

The B pillar bar might need to be set back a little more, and lowered slightly (so it could be used for shoulder straps on a harness).
The X bracing might be overkill, so maybe have one going driver's -> passenger's side, and the other passenger's -> driver's side? I donno.

Tubing wouldn't need to be very big, probably 1" or 1.25" OD, .065" wall DOM or ERW.

Obviously if you have a full cage or back-half/roll-bar, this isn't really needed.

It's just chassis bracing, not a roll cage. Tech inspection wouldn't give two shits about it, now if I had a harness on it, that would be different!

It's also pull penetration (it's a 1/16" thick wall! derp!), they just "look" crappy because of the flux core wire and a little of the zinc that I didn't completely grind off. But I actually have to run a lower setting to keep from burning through, it's not my first weld by far ya know, I only do welding just about every day at work.

There's a fish plate under the tubing that's welded to the angle iron bracket, it's all tied together.

I'd really like a built tremic 6 speed, but that isn't gonna happen for a long time!

Normally these FS5W71C transmissions can take a bit of abuse (about 400 Ft/LBS), but only if the oil changes are kept up and heat kept down.
This stock trans I kept up on it with regular oil changes, donno if I ever got it really hot though, but who knows what the previous 4 owners did to it in the 100k miles that it had on it when I bought it.

This new trans should hold up for a long time (crosses fingers).

Anyway, I got everything swapped now (my upper body is KILLING me), just need to button a few things up still... Then a test drive!
Spent from 4pm to 11pm last night getting the bulk of it done.

One of the tubes... Need the other two in, to form the X, then two forward tubes with connectors to tie it into the mid brace.

I already notice a difference, I can push down on one of the rear corners and the opposite corner comes up with great response, so it's obvious that it's stiffening things up.

Meh, I don't like the fitment of the auto power cages, leaves too much space between the pillars and not enough head room.

I really don't have that much timing drift with cam trigger, even with only 4 trigger windows... Installing that filter cap on the primary trigger input helps a lot.
BUT, it's time to fiddle around with something else, and it would be nice to get rid of the distributor (it does get in the way sometimes)... Plus it's getting harder and harder to find consumables for it.

Hope those little teeth give the sensor enough magnetic change to see, they sure look small. The teeth on my EDIS wheel are much larger, if I remember right the output is something like 10 volts AC. I suspect you'll see much less than 10 volts with teeth that small, but it might not matter if the VR circuit in MS is sensitive enough.
Title: Re: Matt's S12
Post by: seishuku on 11:32:46 PM / 25-Mar-11
From what I've read, it's actually better to have a sharp point, to prevent trigger drifting (too wide of a tooth will cause random triggering as the tooth passes the sensor's magnet).
Though I agree, the tooth should be wide enough to disrupt the magnetic flux and generate enough voltage. With an 1/8" tip, it shouldn't be much of a problem though.

Douche! I thought you said you didn't like the Ford sensors? I could have just given you one of my spares! Anyway, good luck with it. I hope you finally realize the potential of crank trigger vs distributor setups. Meanwhile instead of doing performance mods on my car, I've been battling oil leaks. My driver's side valve cover was spraying oil all over one of the header primaries for like 2 weeks, and I just yesterday got a chance to fix it. Stupid VW's!

Heh, oil leaks and VW's go hand in hand. :lol:

I don't like the usual sensor that comes with most EDIS sets, this one is a little more compact.
I know the potential of a crank sensor, it was just easier for me to mod the distributor than having to go through all this, especially when I was just setting up the 'squirt (it was pretty much turn key).

Yeah, bring that thing over... We'll get that tossed in and jack up the boost!

Title: Re: Matt's S12
Post by: seishuku on 11:14:53 PM / 02-Apr-11
Nah, Megasquirt was way easier than tracking down all the DET electronics and pieces. Though I could have just used the CAS in my distributor, it's the same sensor and trigger disc.
But honestly, after spending a few years with Nissan ECUs and the programming on them, I feel way more comfortable with the MegaSquirt.
There just isn't enough documented on how the Nissan stuff works, it's all black magic that no one wants to share and that just pisses me off. Too many "trade secrets."

I will still have the distributor for a little bit though, but that's only because it's my only ignition source right now (internal coil and ignitor), but it won't be handling the triggering.

I do have new ignitor chips on order, so I can rebuild the coil harness and be distributorless.

If I were to redo this, I would pick up an ATI fluid dampener, and make it a bolt-on reluctor ring.

I did a quick sensor test, but no I didn't have the megasquirt running on it.
Even if it isn't quite where I wanted it, I can fix that by changing the trigger angle in MS... so its not a huge deal if its of a little.

APPARENTLY my fuel pressure was set to 70PSI and not 60PSI like it should have been (thanks Nick for fuel pressure gauge!), so I think that might have been a cause of a lot of my odd tuning issues that I've been having.

My new max duty cycle:
(https://i.imgur.com/RtJQfx5.png)

97% is still really high, BUT that's with a 9:1 AFR and before readjusted the fuel table... So it should be a lot lower than that.

Oh, and ignore the max values on DC and MAT, there were some comm glitches that screwed up those values.

Edit:
Oh, this all means I'm using all of the 528CC/min injector, which means I'm still making a buttload of power... How much exactly? I have no idea.

Agreed. You can pull a whole 2 points of AFR out and still be very safe, and the engine will run much better in the process. When there's that much fuel, it just slows the engine down. After you lean it out, it should rev a lot cleaner and pull harder under boost. MPG will also go up, but who really cares about that right? lol

Anyhow, you should buy the full version of Tuner Studio if you haven't already. I'm hearing very positive things about VE analyzer live, I should get it myself.

Yeah, I've been meaning to buy that for awhile now. I used it for the initial tune, when he had the real-time stuff for free. Very cool piece of software.
I still use megatune logs and megalogviewer to do a lot of tuning too, since that has the ve analyser as well.

Title: Re: Matt's S12
Post by: seishuku on 05:52:35 PM / 28-Apr-11
Hmm... It's getting spark blow out at 5PSI with these coils. I get the feeling it's how I'm driving the base of the power transistors, in that it's not enough current to fully saturate both transistors, which is just a change of a resistor for the ignition pull-up, but I don't really feel like tearing into my megasquirt right now.
Title: Re: Matt's S12
Post by: Big Brother on 10:15:41 PM / 28-Apr-11
In order to find out if you're fully saturating the coils (i.e., set dwell), or if the transistors aren't fully 'on', you need an o-scope. I can drop mine off next time I stop by if you want?
Title: Re: Matt's S12
Post by: seishuku on 10:45:09 PM / 28-Apr-11
I'm fairly sure it's the transistors, it does it even with an unrealistically long dwell.
I'll have to work out the math and see how much current two BU941s take to saturate, then adjust my pull-up accordingly.
If that doesn't do it, then I might need to dig deeper with a scope.

That pull-up resistor was a guess anyway for the OEM power transistor, so it might not even be fully saturating that either.

Post Merge: 11:21:16 PM / 28-Apr-11
Looking at the specs for the transistors again, it says the max base current of 300ma at 2volts for a 12amp load... So at 5 volts, I would need a 160 ohm resistor pull-up to get 300ma.
But that's a little unrealistic, since it shouldn't need that much current to drive both to saturation, at least I wouldn't think.

I might just need to change my base driving strategy a little, and change it to the way the MS manual shows for direct coil drive. I'll just have to remove the pull-up and expose the "right side of R..." deal to the DB37 and have the base resistors at the power transistors.
Title: Re: Matt's S12
Post by: Big Brother on 07:13:00 PM / 15-May-11
Don't forget, the load you're driving is inductive. That may change things a bit, since (at least I think) those saturation curves are made driving resistive loads.
Title: Re: Matt's S12
Post by: seishuku on 05:06:03 PM / 17-May-11
For most transistors yea, it's usually a resistive load for the curves, but I think the BU941 gives for both resistive and inductive (since they're designed for ignition coils).

I think the key is to bring spark A and spark B directly to the DB37 and have base resistors are the transistors.

In other news, I did more work on my oil line adapter:

Still need a thermostat, fittings, a cooler core, oil filter base, etc.
Or maybe just skip the cooler and just do a filter relocation.

Finally got around to driving up to Jay's and grab that R180 he gave me... Got it cleaned up today and a fresh coat of paint, actually wasn't too bad considering how it looked before (forgot to take a pic).

(https://i.imgur.com/krqpG0R.jpg)

Hopefully it's in better shape than my current R180, which has a nasty chatter ATM.

Post Merge: 02:04:40 AM / 28-Aug-11
Something that bothers me, in the FSM they show how to figure the bearing shim sizes based on markings on the diff housing, ring gear, diff center, and the side retainers, but the only thing that has an actual mark is the side retainers!
They have the cast markings for where the numbers should be, but there aren't any there. So either they just mark them with a grease pen and it wears off, or they didn't stamp it very deep.
And if they used a grease/paint pen to mark it, how did they figure that would last long enough for anyone to do any kind of service!?

Bitches.

The only reason I need that info, is because I'm using different side retainers for this diff, as the originals are in pretty rough shape... BUT as luck would have it, I have a matched set from a diff I got from Sterling that are decent enough and are close in numbers to the originals, but I'd like to check to make sure.
I don't want this diff to end up like my current one. :lol:
Title: Re: Matt's S12
Post by: seishuku on 08:49:00 PM / 28-Aug-11
Well, as luck would have it, the side retainers that I'm using have the same dimentional marker as the originals, so I don't need to worry about preload... Obviously I still checked the tooth mesh pattern and backlash.

Now I just gotta take it to work and weld up the spiders, and get it on the car!
Title: Re: Matt's S12

That diff came off the car that a one with the earth for 16 years. The one that was the orginal CA donor for my car.
Brutally rusty.

But, only 70k miles on it.....

Also! Ever considered giving it the fozzy locker treatment, rather than just welding it straight up?
Title: Re: Matt's S12
Post by: seishuku on 09:31:44 PM / 28-Aug-11
It cleaned up real nice though, about 15 minutes with a wire wheel on my angle grinder.
It's just the side retainers and back cover that were real nasty, being aluminum doesn't fair as well as cast steel. Lucky I have good condition spares of both. :lol:

That locking method has crossed my mind, but a full weld is going to add structural strength to the diff, so I don't go shattering spiders.

Edit:
I wouldn't mind going that if it were an R200, but the R180's spider assembly is pretty small in comparison.

Decided to ditch the idea of using a VR sensor for the crank wheel, and bought a new hall effect sensor that DIYAutoTune came out with.
It's a really nice sensor, no VR conditioner to deal with, just a nice clean square wave signal... And I didn't have to change any wiring really, just pulled the lead from the OEM CAS connector and changed a few MegaSquirt settings.

http://www.youtube.com/watch?v=leJmlag2Ciw

Rock solid timing, no real timing drift to speak of, but I am having a little issue with it getting RPM spikes above 4000 RPM... Not sure about that, might just be a sensor alignment issue.
At least I just have the mounting tab for it just tack welded on the original bracket I had made for the old VR sensor, so it's not a big deal to move it a little.

What's this? Finally did the crank trigger, and realized I was right? :laugh:

RE: RPM spikes

On datalog if it's spiking to some ridiculously high number (mine would hit 19,000 RPM), you have a noise issue that needs to be dealt with. For me, this turned out to be related to RFI from the ignition system (I have EDIS) causing false triggers. The recommended switch to suppression wires and resistor plugs completely cured it, it's been perfect ever since. You might try that, as well as shielding the sensor wires really well. Don't connect the shield to chassis ground either, ground it only at the ECU. Also, now that you have a crank trigger there's nothing stopping you fron using those COP's I gave you. Unless you already have...

Passat rear shocks will also work on our rear, with a little modding for the upper mount and a smaller diameter bolt for the lower (or just drill out the shock for the S12 bolt).

Nick: I would have had a crank trigger sooner, if I was able to get that VR conditioner working (don't know what's up with that thing), then they came out with that hall sensor... Then I found out that the hall sensor doesn't sink enough current to properly run a 2.2 input, then I got a conditioner board. :lol:
So it's working better now, it still gets some misses/spikes around 2800-3500RPM, BUT it gets better when it's warm? Not sure what's going on there.
It's all properly shielded, OEM shielded cam sensor wiring is used with the shield extended all the way down to the sensor... So I'm pretty sure it's not RFI, at least not from the ignition.
I'm thinking it's probably electrical noise, since the sensor and conditioner board are both powered off the +12v that powered the OEM cam sensor, I've just been lazy and haven't tried the filtered +5v from the MS.
Plugs are factory resistor plugs and wires are old OEM, but I'm pretty sure they're suppression type. I didn't pick up much noise on the o-scope at least, plus my alternator is kinda jank and needs to be replaced.

Edit:
Matt Cramer told me that some times the sensor can be a little sensitive to sensor alignment, so I might play with that a little.

Oh, and I don't have any filter caps installed on the opto input circuit, so that isn't doing any favors right now either, so I might try putting one back in there.
Title: Re: Matt's S12
Post by: seishuku on 09:12:53 PM / 09-Nov-11
Well, I moved the sensor to the Megasquirt's filtered 5 volt power supply and so far I haven't noticed any spikes or misses on a 18 minute drive at various RPMs and loads.

I should know for sure tomorrow, I usually catch a few misses driving to and from work.

I need a new alternator. :lol: Noisy bastard.

Yep, all seems well with the crank sensor now and power delivery is WAY smoother than it ever was, even with the original unmodified OEM hardware.

Next up is coil on plug, then completely remove the distributor.

Then I need to pick up a new alternator before this one goes out, then a better fuel regulator... One that actually stays set. :lol:
Title: Re: Matt's S12
Post by: seishuku on 09:46:46 PM / 13-Nov-11
lazy weekend... got the megasquirt modded to hopefully better support the ford coils (spark output right off the processor via resistor, instead of going through the led transistors with a pull-up).

It's still running the distributor just fine, so I don't think the Ford COPs will be a problem. I could be wrong though. :lol:

I also removed all the old additional circuits that I had for the 2nd trigger input and launch control (not that I really need it).

After I get the coils working, I'll have to make a plug for the distributor so I can remove it.

So I'm going to try to do some more work on my turbo manifold.
(https://i.imgur.com/3znnSI1.jpg)

I modeled the tube intersections in 3D today and made a cutting template, since I don't have a way to do a rig for my band-saw.
So hopefully tomorrow I'll have some parts made up for the merge collector for a T3 flange.

Hmm... It would seem that I can't quite get the cut that I want with my band-saw, at least not with the cutting guides that I made.
I might have to make two angled jigs, but it's not an easy set up on my saw.

Maybe I should just cut them on the mill at work, which might be a little easier set up and more consistent.

I also might have to buy a length of 1.5" tube, as I don't have quite as much material as I thought. :lol:

I did another quick street tuning session, because I was getting a slight miss in the upper RPM range... Seems it was a little lean...
So it's wanting 107%+ injector duty... This thing keeps wanting more and more fuel.
If my calculations are correct, I'm pushing 330BHP... With room to make more, if I get bigger injectors.

WTF? :lol:
All this on a "big" T25.

Post Merge: 12:28:10 AM / 02-Jan-12
UNLESS the misfire is causing it to put in more fuel (misfire = unburnt fuel = more oxygen in exhaust), which would mean that it'll just keep enriching it until it can't put any more in.
Maybe tomorrow I'll close the gap down more on the plugs (I think it's at .035 right now), and give it a little more dwell (at 3.5ms now).

They're 450CC @ 60PSI, which makes them 528CC. I'm thinking I really need something in the 700CC range.

A big T25 is just the T25g from an S13 SR.

Well, for some reason this morning one of my heater hose clamps let go, or the hose has a small hole it in... I donno, either way I slipped the hose on some more and tightened the clamp, seems to be holding now.
Probably should replace them some time.

I also picked up a new voltage regulator for my alternator, should be here tomorrow. Hopefully that will fix my alternator's excite probably (won't charge until after 2000RPM), and the 15volt output.

Playing around with different ways to control boost and be reliable, so far I've found that a helper spring on the control arm works WAY better than a pneumatic type.
(https://i.imgur.com/KM7m8PT.png)
As you can see on the MAP and boost/vac graphs, it nearly holds the peak boost all the way... Before it would peak to the set boost, then bleed off to spring pressure (7psi).

Power feels way better... I can brake/boost at 40MPH and do a burnout. :lol:

Unless you want to do it, then I'll ship it your way lol
Title: Re: Matt's S12
Post by: seishuku on 12:47:50 AM / 19-Feb-12
Been there, tried that. ;)
Unfortunately I wasn't real happy with many of the replacement trigger discs, the only one I've ever been able to get to work correctly was my modified stock disc.

Honestly, if I were to do it again, I wouldn't weld on the 36-1 wheel the way I did... I was careful on how I did it, but welding heat and a rubber bonded balancer don't usually mix.

If you really want to do it right, pick up a Ross or ATI damper pulley, they both have bolt on accessory drive pulleys and could bolt on the wheel no problem.

Of course those are a little pricey, worth it IMO.

Edit:
Of course, maybe I'm just too picky... With the trigger discs, the engine runs just fine, but the timing drifts as the RPM rises... I was looking for rock solid numbers, which apparently can't be done with just a cam sensor.

Well, I got the pump replaced... Hopefully I don't have to reseal it, I didn't realize that I was out of RTV until after I had drained the coolant and had the old pump off.
SO... I had to use some high quality 100% silicone caulk, not really my first choice, but I think it will be ok.

If I have to reseal it, oh well... Not a huge deal.

I also need to flush my coolant, get some fresh stuff in there. There was a small hint of oil in it from the rebuild (yes I reused it, coolant is expensive!), but it still does the job.
I at least strained it, there was some particles in it.

Well that failed. No output at all with that regulator, which maybe it's a bad reg? I donno.
I don't really want to return this one for yet another exchange, then have to disassemble the alt again (it's a pain, but I'm pretty good at it now!)

The fuel gauge is just one that I could find that closely matches the stock sender, a 90 to 0 VW type I think...

Getting tired of my modified stock steering wheel, so I made a new one...
(https://i.imgur.com/7cWlGBh.jpg)

Just gotta modify the original wheel's hub with a flange to bolt this one on to, which if I ever get another wheel it should bolt on too (same bolt circle as grant and others).
Not sure what to do about the horn though, not like I really use it...

Anyone know how big the stock wheel is? I don't remember, but I was thinking like 16" or something... its huge either way. This one is 13".

BTW, I wasn't able to use the DSM center section... not with out a slight mod. I didn't think of it earlier, but because the DSM has a smaller compressor wheel, the recess for it in the CHRS is smaller. Oh well, the old housing didn't clean up too bad.

Yup, and cars these days tend to wear 16 or above wheels so neither I nor any of my buddies can use them. What can you offer? I paid $400, and only used them for a couple months in 2010. They're still pretty new, if I could get $200 worth of money or stuff back out of them I'd be happy. You know you want studs this winter! How about you fix a few laptops for me? That small PC Jamie bought keeps BSODing, it's pissing me off cause I need it for tuning.

BTW, fuel injecting the Mini is gonna happen before I leave. I dropped the motor in last weekend, just finishing up odds and ends. Last things I need are another MS, fuel pump, regulator, and a spacer plate to hold the injectors right after the TB. I already have billet fuel rail stock, and I'm sure I can hack some lines together out of something.

Since it will also have EDIS, that means I don't need the MSD 6A that's currently in it. Anyone want dibs on it?

Put new 2GB memory card in the small notebook, seems stable so far.

I'll see about getting an MS drop shipped to you in about a week or so, it would need the EDIS mod done to it of course.

Since I don't have your email address for some strange reason, here's the dimensions of the TB for the Mini. Turns out it's a 50mm job, hope that won't be too large for a 1293cc monster! lol

Throttle plate opening: 50mm
Stud pattern: 9mm stud holes on 60mm centers
Outer dimension of the TB: about 80mm (square)

I seem to recall the SU pattern was 65mm, hopefully that won't pose a problem with the adaptor.

Post by: Big Brother on 09:57:52 PM / 11-Oct-12
What if instead of using the stock studs in the manifold at 65mm, I remove them and rotate/reloacte them? That would allow us to take the studs from sort of an 'X' pattern and change them into a '+' (cross) pattern, and sink them into the adaptor on the other side. Then we can put the pattern of the TB into the adaptor however we want, and they won't interfere with each other. Only problem is I'd probably have to use 2 really small ones in the top, or they would interfere with injector positioning.

How about you just make sure it has the right size hole in it for the manifold, and I'll drill it myself? I won't have the intake in my hands for another 2 weeks anyway, so we have plenty of time to mess with it. I'll bring it along next time I stop by.

Post by: seishuku on 11:34:27 PM / 27-Oct-12
Ah, cool.

A small update on the S12, I've decided that I want to do something for the front suspension... I don't want to go hybrid, because I want to keep the suspension mostly stock, but I want something adjustable.
SO... That pretty much leaves me with going to a weld-on kit.

Seems like a no-brainer to me, $200 for the Techno Toy Tuning kit... Probably 300 or 350LB/in springs (suggestions?)

It's going to be set with the sleeves in a neutral position, so I can raise or lower.

Mainly raise for now, to match the stock 300LB/in Passat springs I got out back, which lift the rear about an inch (my camber fix :lol:).

To aid in setting the coil-over sleeves, I made these:
(https://i.imgur.com/7xWiGRA.jpg)

Tightly clamp those to the strut tube, get vehicle weight on it... Mark it, weld it! Simple.
Maybe sell them to someone after I'm done with them, help someone else out doing the same thing.
Title: Re: Matt\\\'s S12
Post by: seishuku on 10:11:57 PM / 31-Oct-12
Well, the suspension parts have been bought... Went with 10" long 300lb/in springs, on T3's recommendation.
The spring rate and length are more for an OEM like height and suspension travel, mainly the latter. Retaining proper suspension travel is VERY important to me, not lowering. :P

I also picked up a generic cast T3 manifold for my SR, more to come on that, still collecting a few parts for that.

Well damn, that was quick.

Looks to actually be a fairly quality casting, came with gaskets and everything... Only issue is that one of the studs they sent with it are threaded incorrectly, but that's minor considering I only paid $79 for it (free shipping too).

Assembled...

Won't be able to use the internal wastegate though, the actuator is too big and will hit the valve cover.
So... that makes the exhaust a little more difficult
Title: Re: Matt's S12
Post by: Big Brother on 11:46:27 PM / 01-Nov-12
FFS, it took you all of 3 seconds to tear my damn Bug apart! :idea:
You best be able to put the exhaust back together when I need it back....
That the manifold from my link, or did you find a deal somewhere? You must let us know how much improvement it makes over that pitifully puny T25, of course.

For the wastegate, you can always reclock the turbo. If the bolt holes for the actuator don't line up, it's possible to drill/tap new holes in the compressor housing to accommodate. Failing that you'll probably end up with a chinese external, since I know you're a cheapskate (worse than me most likely). I'd lend you my Audi external gate, but it's being saved for the Corvair.

Lastly, here's what I came up with on the spacer plate you 'jetted me.

(http://miniman82.4t.com/car%20stuff/mini%20manifold/IMGP5880.JPG)

Got on the Bridgeport, tilted it at a 45 degree angle, then used an endmill to carve out a pocket for the injectors (all freehand mind you, no CNC shite here!). After that, I guessed at the position I wanted and drilled some holes. I thought I screwed myself at first because I broke through right at the edge on the other side, but it ended up working out well because all I had to do is grind a slight recess in the manifold and they are well hidden from the airflow. The tips barely protrude at all, so that's good. It's secured with allen head machine screws, sunk into the aluminum.

Here's a few shots, looking up the head side of the runners at the TB side. I have a choice between 281cc or 317cc Audi/VW injectors. I read that these are dual cone jobs, whatever that means. They have 4 holes, disc style. Pico body are the only ones that will fit, Ford ones are out of the question due to space. Not a big difference between the two injectors flow-wise, I suppose I'll go with the 317's in case I put a hairdryer on it later. Hope it's not too much for the litte 1293 to handle. :evillaugh:

Hey, you said I could! :P

It wasn't the one you links, but it's a similar style... Few bucks cheeper too.
I just picked up an EMUSA external gate, it was only $50 and the few reviews I read said it was fairly decent.

When removing the swing valve housing, one of the studs did break, so I had to fix that... But other than that, it should go back together no problem.

The injector adapter looks really good though, looks like it should work perfectly.
The 280CC injectors should be good for around 90BHP, so those might be enough if you ever super/turbo it... The engine only makes like 60, right?
Title: Re: Matt's S12
Post by: Big Brother on 11:05:32 PM / 02-Nov-12
Yeah, the studs were beyond their prime anyway. I like replacing them with stainless ones, so you never have to deal with it again. BTW, don't loose the special washers that came off the header. They came from a 20v Audi turbo, and are very high quality. Put them in a bag in the car or something. I used the same ones on the primary tubes coming off the heads, and the nuts rusted out from around them while they were untouched.

A stock mini makes 65, mine with a bigger cam and porting should be closer to 75. I figure an honest 100 would be great with a small turbo, so that's why the larger ones. Any more power than that and the gearbox starts taking a beating, and I need this rebuild to last a while. 100hp in a mini is quite a bit, it would be fun to drive.
Title: Re: Matt's S12
Post by: seishuku on 03:55:28 PM / 05-Nov-12
Hell, stock power is fun... You'll just have to rebuild the gear box with some nice fat straight cut gears! :lol:

Got the wastegate today, $70... Same brand as the manifold (EMUSA), definitely seems to be a higher quality knockoff brand than what I'm used to seeing.
I'll have to break it down and inspect everything first before use... I'm told just about everything on it interchanges with the TIAL that it's a copy of, so if the diaphragm is junk, I can at least get a good replacement.
(https://i.imgur.com/AhoG6Zw.jpg)

Building the downpipe should be interesting... I may need to cut a clocking flange for the gate though, otherwise maybe I'll just open dump it.

So far I'm $150 into this T3 upgrade, not too bad... Hopefully I can get the tubing for the downpipe locally, getting tired of ordering and waiting.

Mines a little different, but still an Ebay copy from before (That they have subsequently changed because they were able to prove that it was lass than 1% different to the real thing).

Title: Re: Matt's S12
Post by: seishuku on 10:58:16 PM / 09-Nov-12
Well, that's about 1", there's still at least another 4" down travel, so realisically a 2" lift would probably be it with out longer shocks... Otherwise you'll be hitting the shock's top stop all the time.

2" would probably be pushing it for tie rod angle though.

But like lowering, lifting will cause bump steer issues too... I haven't noticed any yet, but I need to find some nice whoops to test it out on.

Can't complain about a $230 suspension upgrade, and now I can change out to any spring rate I could ever want now.

Well I took another stab at getting the Ford coils running, this time with a different set of coil drivers.
They run better than before, seems the new drivers at least take less current to saturate than the old ones I tried, but I still get a weak spark... So either the coils are junk (junk ford parts?! NAAAAH), or the coils need WAY more dwell than I ever expected.
I don't want to keep jacking up the dwell and risk burning something up really... Soooo... Either I need to try it again with a different set of coils, or maybe pick up some known good SR coils.
Though I can get brand new VW coils with built-in drivers for fairly cheap, so maybe that might be the better route. I donno.

In other news, the battery for my laptop decided to not charge anymore, so I have a non-portable laptop for now... Oh well, the battery was at 50% wear anyway and didn't have much discharge time anymore.

LOL they're off a vg! you need 8" of extension to get the plugs on them!

Ok, got another set of ford coils, original ones this time (the blue ones are aftermarket "high performance")... Gonna see what happens this time, if they do the same thing, then I guess it's time to find different coils that I know will work.

I also cleaned up some temporary stuff that I did when I switched over to the crank trigger, mainly moving the sensor amp to inside the MegaSquirt case, before it was wrapped up in with the other harness wiring. :lol:
Nice project and I like your engine  :yay!:

Yea a little too rich for me, unless I could find some used ones on the cheap.

After a little thinking, I wonder if maybe my problem is not having a condenser wired in and the voltage spike is screwing up my crank signal.
Something else to try anyway.
Post Merge
Well that was a bit more successful than before, seems the condenser might have done the trick... The bad part is that while I was datalogging, something got to the serial line is corrupted pretty much ever one of my MegaSquirt settings, including running dwell... So one of the coils may be fried (though it could have been a weak coil in the first place).

So, probably tomorrow, with the settings restored (thankfully TunerStudio keeps restore points), I can test again with the other blue coils and see what happens.

Hopefully the ignitor didn't get damaged.

Time to dive into data logs...
Post Merge
Must have been a bum coil, blue ones work ok... BUT, it's still getting misfires on high boost. Even at dwell times way higher than they should ever be. :\

I swear I'm doomed to use a distributor forever. :lol:

I think it might be time to pick up a 4 tower wasted spark coil, unless I come into some money and grab some LS coils... Maybe tax time.

Well, there was never any risk to the MS it self, only potential for cooked coil/ignitor.

I just don't get why it won't work correctly, as far as I know, there are others that have used this combo before... Though it isn't common at all.

Plug wires and you can kinda see my block off plate for the CAS, it's made out of Delrin and I'm not sure if that will be high enough temp for that location, so it'll probably be redone in aluminum.

Just the coil, MS is still in complete control... I like my spark cut. ;)

I'll probably just keep the spark plug ends, but I'll uncrimp the coil side and trim to length.
I wish I could reuse the SR spark plug ends, but they're moulded to the cable.

I will probably have to fashion a seal for them though, they do fit rather loose in the plug holes.

I have limited space where the coil can be placed, I have a big old top mount T3 turbo and exhaust parts I have to keep away from.

Hyundai coil set is here, pretty nice setup actually... And Denso makes the coils, so no worries about quality (not in my mind anyway).

Here's how it came:

Modified the bracket that ties the intake plenum to the head, welded on a part of the bracket that came with the coils... Fits quite nicely, just need to shorten up the plug wires a bit and clean up the wiring.

Yeah, I thought about using those too, or the GM 4 tower single module, but those are both fairly bulky like the Ford coil too.
At least the single 2 tower GM coils are separate, but still a little big for what I was looking for.

I'm pretty happy with this set up though, I just need to strengthen the bracket a little more though.

Edit:
Oh, you probably mean LS1 coils... Yeah, I would like a set of those too, they have coil drivers built-in, but they're way too expensive for me and I didn't want to get used coils.

Well, just got done rebuilding my front calipers... They really cleaned up nice, considering they were factory originals, wire wheeled them and hit it with some high temp black paint.

Bad thing was the seal kit included a dust seal that didn't fit, not even close... I made it work though, not quite the way I would like it to, but it's better than a torn one. :lol:
At least the piston seal was correct, so no leaking brake fluid everywhere... That was actually making stops first thing in the morning a little hard at first, because sometimes the fluid would get on the rotor. :\

Didn't get any pics though (hard to use a camera when your hands are covered in brake fluid), but it was a really simple process (unlike the rear calipers).

I'm still not sure what I was making with the T25, but it has to be at least 260WHP, so I should be able to pull 300WHP with out much trouble.
Injectors are going to be a limiting factor here though.

The biggest thing is the exhaust flow is MUCH more than it was before (T25 chokes the crap out of the exhaust), so power band will be WAY wider.

It revs cleaner too, with the T25 it would be a little stuffy and rev up a little slow, it's nice and quick now.

Title: Re: Matt's S12
Post by: seishuku on 11:19:38 PM / 19-Jan-13
Megasquirt isn't running a MAFS, so no worries there... The injectors were nearly maxed though, not sure how that's gonna work out with this turbo though, only tuning will tell.

If I remember correctly, the turbo is off a Saab 900, it's a 50 trim T3, the same that's used on the turbo Ford Thunderbird as well (though the discharge flanges are different).
Turbo Dodge Caravans I think got a slightly smaller trim T3, but those have a different turbine inlet flange.

Depends on how close they are to 100%, but I don't know what pressure I'm going to run either.
Supposedly 530CC injectors should be good to 350WHP,  but then again according to Megasquirt I was very close to maxing them out on the T25, so I don't really know until I get to tuning it.

Did a bit of retuning... Did a guess at the increase to get it going and it didn't really change a ton, so I guessed right.
Just needed to rework some of the boost transition areas, so my low end isn't all funky.

Impressions so far: Pretty nice, the power comes in smoother than the T25 (which would come in pretty hard), but that could just be the wastegate being a little soft... It's only got the 5PSI spring in it right now (wanted to be safe to start out).

But, even with only 5PSI, it actually feels like it's making nearly as much as the T25 was at 14PSI... So 7 or 10PSI it should be right where I really want it.

Edit:
What I really should do is get a pair of solenoids and set up the Megasquirt to control the boost, with two valves I can do a "push-pull" type setup and could actually use even the smallest spring and not worry about the exhaust pressure pushing open the wastegate.

There's something odd about the springs that came with the wastegate... It was supposed to come with a 4LB, an 8LB, and a 10LB, but the strongest one is the 4LB one I had in there...
I put in one of the others along with the 4LB (it's a smaller diameter, dual spring) and I only get 10PSI tops.

Maybe I should just order some springs from TIAL, I donno.
Or maybe I should just make a new boost controller again.

On the plus side, it holds boost nice and steady and doesn't fall off at all.

I do think I need to up the boost to at least 12PSI or 14PSI.

Yea, I took another look at the data logs... I'm pig rich, still got a lot more room before I hit max on the injectors... Time to up the boost. :lol:

So let me get this straight: I was right about the crank trigger being the shizz, and I've been riding you for how long on getting a better turbo...  Are we learning yet? lol
Also, since I got that turbo from a Saab does that mean you now have a SaabVWNismo turbocharger? ROTFLMAO!


Speaking of progress, I've been working on that injection manifold for the Mini. Here's where I'm at right now:

Block you fabbed got drilled for injectors
made a rail with AN-6 fittings
Had to make an intermediate plate to mount the TB because of hole placement, 3/8" aluminum plate

Having a hard time figuring out how to get a TPS for this thing, from what I gather it's 200SX? Heading to the parts store tomorrow to figure it out. After that I need to get a set of GM temp sensors, mount the IAT in the side of the block opposite the linkage, then get it in the car and run the water lines to/from it. Getting closer!

Got a complete fuel system for the Mini for $100 too- 25' of steel 3/8" hardline at Autozone cost me $20, F-150 pump for $50, some random fittings for $30 and I had a regulator and -6 braided line sitting in a bin in the garage. Also found a spare 6' Megasquirt harness I thought I lost, so I guess I'm set. Now if I could find some time...

Yea yea, keep your "I told you so" to your self. :P

That thing is looking good though, I figured you would have to make an additional plate to mount the TB to.

With as small as the throttle body is, I'm going to say it's more than likely from a GA16DE 200SX, which also came in the same year Sentra, so pretty much any autoparts store should have a TPS that will work.
Title: Re: Matt's S12
Post by: Big Brother on 10:22:25 PM / 26-Jan-13
Yep, that's what it was! Found it under a '91 year car.

I was confused as all hell for the longest time, because I had a TB in the (Waukegan) garage that I pulled from a Saturn back in California. When I got unpacked here I thought it was that one, but for some damn reason no Saturn TPS would fit it at all. Did I get this thing from you and just forget about it or something? My brain is a bit fried from all the weed I used to smoke, I guess. Stopped by Pick n Pull and got the pigtails for the TPS, injectors and water temp sensor. I'd have gotten one for the coil as well, but I spotted a nearly new VW 1600 engine and had to have it. I know I don't need another one, but it was a very low miles factory replacement engine. They normally cost $1,300 to buy, so when you can get one for only $200 you don't pass it up. Probably just flip it for $500 and make a profit. Also saw a Previa SC, I'm going back to pull the 'charger out of it in a couple days.

Post by: seishuku on 11:14:18 PM / 26-Jan-13
You and your VW engines... Hell, I wouldn't pass that up either... That's a steal. :lol:

That throttle didn't come from me though, I wouldn't have something that small... Only one I have is the 60mm KA throttle.

I was eying up one of those superchargers way back when I was looking to go forced induction, but it's a really small displacement... So I ditched that idea, but who knows, it might be kinda cool on something else... Maybe the Mini?
Title: Re: Matt's S12
Post by: Big Brother on 05:59:28 PM / 27-Jan-13
Well shit, I have no idea where it came from then. I don't remember ever removing a Nissan TB at the junkyard, so if it didn't come from you it's an unsolved mystery. You're right about those chargers are pretty small, if you don't like the SC12 I have an IHI twin screw from a Mazda Millenia. How about a twin charged engine in your ride?

If I'm reading these compressor maps correctly, at 1.8PR the T3 should be flowing as much as the T25 at 2.0PR (about 18 LB/min).
So at 11PSI I should be at about the same power that I was with the T25, though it'll probably be a little more considering the exhaust isn't being as restrictive as it is with the T25...
At 9PSI (that I'm at now), I'm running about 70% injector duty, so at 11PSI I'll probably be closer to 80% and be at my max again.

And it's 'efficient' up to around 18 psi (2.22 p/r) supposedly. I say 'efficient' because it was making some pretty hot air at only 1.9 p/r on my car, I recorded IAT of nearly 300*F at times. Granted that was during summer and sans intercooler, but still. I'd be interested to know what your IAT looks like at similar levels of boost (12-15 psi), because the lack of intake cooling was certainly the reason why I didn't break into the 12's last year. That 1.9L VW motor has gone as far as it's going to at this point, it's time to evolve... Good thing I sent you those parts, huh? Should be a much improved setup with that barrel cooler and meth spray, maybe I'll even hit high 11's? Never know, I build the motor to take 20 PSI... muhahahah....might be E85 time.

I got a good log that shows a 30 degree rise over a 10 second pull... Went from 10 to 40. :lol:
I don't think it will be much worse than the t25, which at full tilt was pushing 150 degree temps. At least that's the highest I ever saw.

I made another manual boost controller, just need to install it and wait for the roads to clear up a bit.

Balls!  I can definitely relate, the Mini had a warped block deck back in CA and it's taken me until now to get it sorted out. Mainly because at the same time I decided to have the thing bored +.020, but what's the point of a teardown if you don't build it back bigger right? :idea:

Anyway, here's how things sit with the engine right now. Fabbed a bracket to hold down the fuel rail, and I'm picking up the last of the fittings today. Still have to figure out where the regulator is gonna sit, probably near the radiator.

As you can see, the air filter just barely clears everything. And ignore the AN fittings going to a non-clamped hose, I was just using up what I have and it's only a breather line anyway. Spool gun I bought is definitely worth it's weight in gold on this project, welding aluminum is the shiz! Only thing left after this is finishing the hard lines and fitting an exhaust, then it gets fired off!

True.... for some reason I thought the carb was smaller, like a 32 or something like that.
Hey, its a project car, wouldn't be much of one with out noise.

Well, so far the head gasket seems to be manageable as long as I keepthe revs low and out of boost.
I can't help but wonder what the head or block looks like where its leaking, probably my biggest worry is a huge gouge in the surface that I can't fill.
Obviously the best thing would be to deck the block and head, but I can't have that kind of down time or cost.

I guess I'll have to order the head bolts and a cosworth gasket, find a weekend to pull the head and find out.

You mean you don't have studs on it yet? I suppose this means the stockers are TTY? The stud kit is only $132 from ARP, seems like good value for money if you mess with the top end enough? Hope you're not having the issue I had with the Mini, I went through 3 head gaskets till I conceded that the block was warped between #2-3 cylinders. Best to fix it right at once, to avoid additional down time.
Title: Re: Matt's S12
Post by: seishuku on 01:36:27 PM / 02-Mar-13
I was thinking of getting studs, they are pretty cheap, I'm kinda on the fence with them though.
Yea, the stock bolts are TTY, I reused them though since they've never been out before... I'll generally reuse a TTY bolt at least once, after that they're junk.

Nothing should be warped, it's never been over heated and everything was done by the book when I rebuilt it. I'm 90% sure it's just a junk gasket since it's only leaking coolant/compression and nothing more.
No coolant in oil or oil in coolant, it's just pushing compression into the cooling system when in boost.

The only other possibility would be the head lifted, but I'm fairly sure I would have WAY more issues than just loosing coolant/blowing coolant out.

Either way I have a straight edge and some feeler gauges that I'll check everything with when it's apart, especially around #3 and it's water jackets.
The thing I'm worried about is that there may be a path worn into the block or head where it's leaking, and I really can't afford to have things machined (and we don't have the correct tooling to do it at our shop), especially if it's the block that's fucked.

But I'm really betting on the gasket, it was a cheap-o supposed to be OEM gasket and just couldn't take it in that area.
Title: Re: Matt's S12
Post by: Big Brother on 08:20:39 PM / 02-Mar-13
Well, there's your problem. TTY bolts are only good once, then they are trash.

http://www.freeasestudyguides.com/a1_4.html

Once they stretch, you're done. They won't hold a clamping force again, or if they do, not for long. My guess, you took a chance and lost out. Just get the stud kit, it'll save a lot of trouble down the road. I hadn't overheated the Mini either, and it still warped. Apparently it has something to do with the way water circulates around the block, it happens to a lot of the A series engines. I hope it was just the gasket too, but if you reused TTY bolts that's what I'm putting my money on.
Title: Re: Matt's S12
Post by: seishuku on 10:49:07 AM / 03-Mar-13
I guess it's possible, though the factory manual states you can reuse them provided the length doesn't exceed the spec they give, they didn't when I checked them.

Well I feel dumb... For years I thought my alternator was going bad, been putting out 15 volts... I've just kind of accepted this until I can replace it.
At least the Odyssey battery I have can take the abuse well enough.

Anyway, apparently, for some reason, the alternator will not self excite or charge correctly with out the charge light connected...

After hooking up a light to it, and started the engine, as soon as it cranked over, the alternator started charging normally (14.4 volts).
Go figure.
Title: Re: Matt's S12
Post by: Big Brother on 10:31:41 PM / 04-Mar-13
The light is tied into the excitation field circuit...

Who cares about the alternator, something tells me head gasket issues are higher in the food chain right now.
Title: Re: Matt's S12
Post by: seishuku on 12:19:44 PM / 05-Mar-13
There's a separate wire that runs the field circuit, so I never thought much of it.

The car is still drivable, so the head gasket isn't a huge deal (yet), I don't have the money to fix it right now anyway... so no point in worrying about it now.

Gotta wait on the tax return... which will probably cover just this. Thanks Obama.

The gasket, defect in the fire ring.

The really sad part, it wore a gouge in the head.

Not really sure how I'm going to fix it... Ideally I would resurface the head, but not really an option on the weekend.
High temp JB weld? I donno.

There is a chance the new gasket will seal outside the bad area (it's an 87mm vs the stock 86mm), but I'm not going to take that chance without some added insurance.

On the plus side, the block is perfectly straight and the head is straight (though not AS straight as the block, but in spec).

Head and block are as prepped as they're gonna get, head gasket has a coating of copper spray, and the head stud threads have been chased and cleaned.
Pretty much just waiting on the metal filler to harden so I can bring that back flat with the gouge filled, not the way I'd like to do it, but "the math works out", so I'm gonna take a chance. Not that I have a choice right now. :lol:

I'm feeling pretty good about it right now, worst case is the filler blows out and I'm basically right back to where I was, but at least with the studs I can pull the head with out having to buy new bolts (technically the gasket is reusable too, but I don't like that).

Well did a shakedown to get stuff up to temp and bleed out the rest of the air in the coolant, then beat on it a bit.... No combustion leaks at all, so far so good!

I guess only time will tell.

Now I gotta retune my fuel map because apparenty the last time I tuned it things were a little weird, like it wasn't producing what you would normally expect... It would seem my FPR decided that it would ignore proper MAP reference, so I have the FPR off the beetle now and things are much better (besides being rich in boost now).
Would explain why I was running out of injector flow last time too.

Now that all that's fixed, on to a new boost controller:
(https://i.imgur.com/qkAEqPC.jpg)
(https://i.imgur.com/sLtp7bm.jpg)

It's an SMC precision pressure regulator, VERY precise!
Bottom port on the wastegate is connected to boost source, as is the inlet on the regulator, then the outlet is connect to the top port on the WG.
The pressure differential from the regulator is basically adding more "spring pressure", downside is that the minimum boost is still spring pressure, but I could just toss the 2PSI spring (don't ask) in there and let the regulator adjust the whole thing.
Title: Re: Matt's S12
Post by: seishuku on 04:03:17 PM / 28-Jun-13
I guess that regulator has too high of a pressure threshold to work the way I wanted, so I tossed that out.
Now I'm playing around with the apexi avcr that was in the beetle, its a pretty nice piece of electronics... Not worth the $600 price tag though IMO.

The sr is still pullin like a freight train though, 15psi on the t3 is nice... Boost kinda comes in later than I would really like though, maybe changing from the carbon seals to dynamic seals would help some. Oh well, that's what launch control and flat shift is for.
Title: Re: Matt's S12
Post by: seishuku on 05:47:38 PM / 06-Jul-13
Man this boost controller is finicky... With just the bottom port being used on the wastegate, I get annoying boost spikes (way worse than what I see with a MBC) and I can't seem to "tune it out" like they say you can.
Then I switch to using both top and bottom ports, which is better, but while adjusting the controller I got 15PSI with a 62% duty, then it suddenly wants to drop back to 10PSI... WTF?
I didn't test it much past that, but I bumped the duty up to get 15PSI again, but if it starts boosting to 20PSI I think I might be going back to a manual controller.

I could probably get it to do what I want with the gear based boost control and per RPM mapping, but F THAT... Way too many settings to deal with, if I'm going to do that I'll just set up the boost solenoid on the MegaSquirt and let it do the controlling.

That's why I got it for $100! lol

You're right in that it's very advanced, there are simply too many features and it's easy to get lost. Add that to the terribly translated manual, and it could be a recipe for disaster. Took me forever to get it ironed out, but once it was dialed in it was flawless. You just need some more time messing with the menus I think, they are all related in some way unfortunately. Big thing is for it to work correctly it really needs the TPS and RPM signals piped into it, or it has no way to know how to react in time to give you the results you want. I couldn't get it to work at all till I added TPS, a MAp signal alone isn't enough it seems.

Only turbos I build with carbon seals are the old Rajays, and those only see duty in the Corvair anymore.

I do have RPM connected, but it seems it depends on RPM and wheel speed more than anything (for gear based boost), but I don't see how it incorporates TPS. On MegaSquirt its obvious in the DC and kpa target tables, because its pulled in an alpha-n manner.

I think I just need to up the feedback value and fine tune the DC, using both ports on the wastegate helped stabilize it, but I haven't seen if it falls off at high RPMs.

That might be my fault, actually. There's a setting in there that's supposed to counteract spikes, I think it's called start duty or something like that. I had to use it for some odd reason, because it wanted to be lazy on me in the low RPM range. What can happen is if start duty is too high, it can overshoot and end up spiking.

Here's what you need to do:

Reset everything to factory, make sure you have it set up correctly for the engine.
Get it so it will reliably hold the boost pressure you want by playing with boost duty.

Manual written by Confucius say:

"External wastegate spring rate will dictate the boost control range. Because of this reason, please set the spring rate so that max boost pressure can be controlled with a 70% duty cycle."

I take that to mean if you want 15 PSI, put 15 PSI worth of spring in there and hope you can hold it with around a 70% duty cycle. Maybe I'm wrong, perhaps it really means use an 8 lb spring and your 'range' will be 0-16 lbs? No idea, play with the WG I guess until it seems to fall inline like Confucius says. Make your test runs in 4th or 5th gear on the freeway, so boost comes up solid really fast. You'll know right away if it's working; either it'll hold where you want it, fall short (increase duty for desired boost setting), or overshoot (reduce duty). Once you have that done, you can use the start duty to sort of 'tune out' unwanted spikes. So if it's really getting crazy with the cheese whiz in 3rd but the other gears are fine, reduce start duty in 3rd and it should stop happening.

There's about 10 billion other settings to play with, but that's basically what I've done with it. Give it time, get to know how it works. The results are way worth it.

It's not that hard, and you have all the signals you need. I suggest you get the basics knocked out and get it stable, then either get into gear based boost or let it do its auto learn thing. It's fun burning through tanks of gas while you figure it out, just don't get busted!

Nope, only Dodge and only the early ones with 3-bolt compressor inlet- because in the Dodge Turbo 1 engine, it was rigged up like an old draw through engine with the TB before the compressor. That's also the reason why Turbo 1's had no BOV.

Without TPS, the unit has no way to know when 'start duty' is suppose to happen. For all the unit knows 'hey lookie here, I got boost all of the sudden!', with TPS it can better predict how to control the solenoid supposedly. Yes wheel speed/RPM is important for learn gear (I never had wheel speed in the Bug), but TPS is equally important in how it works. For example, without TPS you stab the gas- how's it gonna know when start duty is supposed to happen? My theory is it uses TPS to 'anticipate' start suty coming into play. Or think or it this way: more inputs=more reliable output. That whole GIGO thing coming into play again.

Nothing yet, had to wait like 3 months to save up enough for the turbo. I guess if I have to I can bounce the MS I have between the Mini and the VW, they both have the same parts in them as far as the MS is concerned. Speaking of the Mini, I had to order a new crossmember because the old one was rotted beyond repair. It's the one that goes across the floor, the seats attach to it. Got the new one tacked in before I left the house, so at least I'll have something to sit on when I go to fire the motor. Nearly done with it by now, just have to put the finishing touches on the fuel system and hack together an exhaust.

Yeah, its not a big deal... I actually have it set up more or less how I have the sr20... Just pulls the crank sensor and fires the coils directly, no edis for now.
Was just easier that way since I have spare coil drivers, plus I didn't have to modify my MS to run edis.

Figure out what seats you're going to use?

Edit:
Oh, I did some high speed and low speed pulls, trying to get things as hot as I can... Highest logged MAT was 124F (at intercooler outlet).
Not too bad, not sure I want to know what that is directly out of the compressor though.

It's designed to bolt in between the lower intake manifold and the upper plenum, so it doesn't permanently modify anything.

Title: Re: Matt's S12
Post by: seishuku on 10:11:17 PM / 10-Aug-13
Yeah, it's just that close of a fit... ideally it should be all enclosed and have some kind of seal, but the leakage is tolerable and can be tuned around, and I don't have enough room for a total seal.

Like I said, it's more for the cool factor and the fun of making it than anything, though I am interested in the actual power gain... Not that I can go much more in power, I'm already at 85% of my injector.

holy crap dude. damn wish i wouldve kept up with your thread. you've been busy. I saw the slide plate setup on a 4 rotor build thread that was making the rounds a little while ago. sick as fuck. cant believe you cut those splines on a water jet either. i didnt realive they could do that kind of detail work. Hows the car drive with the slide?

Yeah, I wasn't quite sure if the jet was going to be too big to get that small of a spline, but it does just barely.

I actually haven't drove the car with the throttle on yet, I'm having a hell of a time finding a longer center bolt for the plenum... I think I'm just going to have to make one (haven't had time).

Boost control... Again. :lol:
For the last time, I think.

I pulled out the apexi avcr, as nice as electronic boost control is, there's just way too much work tuning it just for something that should be simple.
I may go back to electronic later on, but it'll be under MegaSquirt control.

Anyway, I have a 5LB spring in the wastegate, which obviously gives me about 5PSI boost...
So what I do is plumb the boost source into the bottom port of the wastegate, then I tee into that line with a air pressure regulator set to about 10PSI and connected to the top port of the wastegate which puts counter pressure and acts as an air spring along with the actual spring.

Result? Consistent boost pressure, as if I replaced the spring... Only I can add as much boost as I want.

(https://i.imgur.com/4jkn4Hh.jpg)

My only complaint is that the boost gain isn't as fast as you can get with an electronic setup, but boost does still come up quick... Just isn't a quick snap to full boost like it was. (which actually might be a good thing for my axles and trans!)

Jesus H. Christ... Just one thing after another... First the starter, then my rear main seal is getting worse, then spark plug well gasket starts pissing oil, now the T3 turbo's oil seals are going (though I guess that's not a big surprise).
On top of that, all this really fucking cold weather is doing a number on my oil, causing all kinds of water build up and the shit ton of steam from the water boiling off is causing a lot of oil to blow out the valve cover vent... Either that or I got a crap load of blow-by (need to do a compression test).

UGH... I think I need to look for a back up engine or something, that or just get a new(er) car.
Title: Re: Matt's S12
Post by: Big Brother on 09:49:00 PM / 04-Feb-14
That turbo never leaked a drop since I've had it, gotta be something else wrong like water in the oil or excessive pressure.
Title: Re: Matt\'s S12
Post by: seishuku on 12:16:07 PM / 05-Feb-14
Well its definitely leaking oil past the turbine seal, its got oil coming out at the center section... I gotta pull it to see if its blowing more into the exhaust.
I'm pushing it harder than you were though too, so it doesn't surprise me too much.
Weird thing though, it wasn't leaking this morning when I left for work... so maybe some coked oil broke off and wedged the seal a bit and then came out. Not very likely, but could happen.

There is some water in the oil though, I've been battling excessive condensation since we've been having this super cold weather.
Its at least not coolant anyway, doesn't taste like anything.

Ok, so I figured out that it doesn't give me the big cloud of smoke if I stay out of boost (been super cold again for the past few weeks)...
Now today just a little before I get home, I give it the full beans... Pulls hard as fuck like it should (never had any issues there), but no smoke (other than the usual visible vapor from it being cold).

Now, my oil may have been a little warmer than it was before when it was blowing oil/smoke... what at the chances that being cold that my oil pressure was too high and it was just pushing oil past the turbine seals?
I know that with as cold as it is, I really need to be running 5w30, but I'm too close to my oil change interval to go thinner now (plus we have warmer weather on the horizon now, finally).

I'm thinking maybe I need to change to 5w30 full time, then get an oil cooler so the hot summer weather doesn't cook everything.

And yes, I do have an oil restrictior installed at the turbo, though it's not the recommended .035" (I think), it's a loose 1/16"... Although the T25 never complained about over oiling.

I donno, maybe it's just a mix of things and it's just all adding up and causing problems...
Title: Re: Matt's S12
Post by: Basic on 06:52:05 PM / 11-Feb-14
i think you are probably correct in your mix of things.

What do your oil pressures look like (if you have that hooked up)?

Could you maybe try a different restrictor and see if that helps? Not too terribly expensive if that's all it is.
Title: Re: Matt's S12
Post by: seishuku on 08:25:56 PM / 11-Feb-14
Lately I've been seeing 85PSI cold... I've seen 100+PSI before though (gauge maxes at 100psi).

I have the correct restrictor for the the turbo, .060", the .035" was for ball bearing turbos... But maybe I'm over the normal expected pressure even with the restrictor.
Title: Re: Matt's S12
Post by: Basic on 11:53:01 PM / 11-Feb-14
Man that's some high pressures. Is it really going to warm up that much that soon where you are? I know here in OK its kind of a pain because as an example we may have 70 degree weather one week and be in the teens the next. That's how it has been this winter anyway. Last week we had lows down in the low teens, and this weekend its supposed to be up near 70. Big swing in temps.
Title: Re: Matt's S12
Post by: Big Brother on 12:43:05 AM / 12-Feb-14
Your oil pressure is way too high. You're wrong for not already having 5W-30 or even 0W-20 in the crankcase during the cold winter months, I doubt the turbo is to blame here. Most likely the cold oil is like molasses and is backing up in the drain line, it's gotta go somewhere so it's seeping out the turbine seal. Out of curiosity what are you running now, please don't say 15W-40 or something heavier...
Title: Re: Matt's S12
Post by: seishuku on 03:55:25 PM / 12-Feb-14
Yeah, the next few coming days it's supposed to climb into the upper 20's, then hopefully the next few weeks it'll make it into the 40's.

Ha, I don't even think my crank would even turn with 15w40 in there... No, I normally run 10w30, but normally it doesn't get this cold here either, except for maybe a few weeks in the middle of winter where it's -10 or whatever... But it's been like that for the past two months!
Remember, this isn't SBC where you could fit your fingernail between the crank and the bearings, it's pretty tight... But again, normally 10w30 is correct for our weather here, but this wasn't a normal winter.

Old ones were getting crusty, and lord knows if they've ever been replaced.

They're Techna-Fit brand, number NIS-1150 if anyone is interested.
Obviously the fronts fit, I'm not 100% sure on the rear though, I seem to recall that those seal with a copper washer and these lines appear to be inverted flare... BUT I think if I add a copper washer, it'll work... It's been a long time since I last went poking in the rear (huh huh).

And, some ECU awesomeness:

Ok, this has me stumped...
Engine keeps building a bunch of condensation, I'm getting a lot in my catch bottle... It's pure water, not coolant (no taste at all).
The engine also has a slight leak down issue on #1, maybe 10%... I'm not sure... It's not burning oil that I can tell (oil level is where it was a month ago when I changed it), but the top of the piston was wet... But that dried up, I'm assuming it was water.

The engine make good power, it's not really running funny, though the idle is a little wonky, but I'm fairly sure that's attributed to the recent Megasquirt upgrade (haven't tweaked everything yet).

Where the hell is all this water coming from!? It's a short drive to work every morning, but I always let it finish warming up (usually wait until oil pressure is about 30PSI at idle), and the same when I get home. That should be enough to "burn off" any condensation.

It's not enough water to turn the sump oil milky, but I get mayo under the fill cap, out the valve cover vent, and at the PCV valve. It actually produces an almost alarming amount of steam.

Edit:
And I'm like 99.999% sure it isn't coming from coolant, my cooling system is at the same level, no changes at the reservoir (other than thermal expansion), the hoses have no air pockets... And I'm pretty sure the steam would have a sweet smell or taste if that's where it was coming from.

I'm also not getting any kind of smoke out the tail pipe, nothing blue, nothing black, nothing white (except when outside temp is low enough).

Operative word being 'should' be enough to burn it off.

We just came out of the cold season, so change your oil if you haven't already. It's likely that you have a lot of water in the crank case, built up from never getting hot enough for the last 5 months or so. Now that the engine can actually get hot, you're seeing all that water get released from its slumber. Remember: water temp is not oil temp, just because the coolant got hot doesn't mean the oil followed suit. In my Corvair the heads never got above about 200*F during winter, which for an air cooled engine is stone cold. The air doors never opened, and the heater sucked. Same thing happened, I had to change the oil when it got warmer outside and there was mayo everywhere. The VW actually clogged all its breather lines with mayo one year, I had to take them off the engine and whip twirl them around to get it all out! Mayo=not enough heat, so go out to I-90 and burn it out.
Title: Re: Matt's S12
Post by: seishuku on 09:35:03 PM / 10-Apr-14
Well cold idle oil pressure is 80PSI, so down to 30PSI is fairly warmed up. My water temp is up to 180f by the time oil pressure is down to 50PSI.
Anyway, today it all seems worse, and it's blowing smoke out the valve breather when cold, so it's not only water vapor, but also exhaust gas. :grumpy:
Cylinder leakdown didn't seem enough to cause THAT much combustion leak, but it's also not drawing in oil either, so I don't know what's doing on there.

On a lighter note, I got the new brake hoses installed in the rear now, they fit perfectly and as I suspected I had to reuse the copper crush washer.

Title: Re: Matt's S12
Post by: seishuku on 04:05:20 PM / 11-Apr-14
I guess not.

It's not the head gasket though, the other cylinders are a solid seal, no oil leaking, no coolant leaking. It's just rings on #1.
I wonder if something got in there and gouged up the bore wall and that's where it's blowing by, but I would think that would have made noise.

I thought about a VW motor in there, not exactly a quick fix for my current problem though... I guess I'll just have to deal with it for now, and maybe keep an eye out for a decent/cheap S14 SR20 long block or something.

Interesting... it doesn't seem as bad today coming home from work.
Its still blowing exhaust out the valve cover vent, but not nearly as much.

I wonder if it might be a stuck ring, or maybe some how the rings rotated to the point where the gaps are nearly on top of each other (not likely).

Whatever, I don't really care anymore... just gonna toss a catch tank on it and keep going. :lol:
Title: Re: Matt's S12
Post by: Big Brother on 12:30:19 PM / 15-Apr-14
lol, as long as it don't leave you stranded at some point what's the harm I guess.

Update on the Dodge: went through 2 recon heads with a place based in Texas, but they both had issues I wasn't comfortable with. First one had a small crack in one of the water passages, this recent one had some welding done to the intake ports (probably to fix cracks) and they didn't do the machine work correctly. There was a gap under both the new intake seats, so I don't think they went into the casting all the way. That and a generally unfinished look to the welding repair itself, like not using a die grinder at all to clean it up and blend back the port wall, was enough to turn me away. They claim that when they machined the counterbore for the new oversize seats it leaves a small step from the old counterbore, but I was able to insert a thin piece of metal across the entire width of the seat so I don't trust it. Not like they are going to pay the mechanic for his work when it drops a seat...

Long story short I found an old post from last year on a forum where a guy was selling an NOS cylinder head for only $260 shipped, he still had it so it's on it's way from Oregon now. That plus a new T3 to replace the tiny TE04H Dodge decided to foist upon this great engine, and I should be ready to rock soon. Now I just need an intercooler...

That's how this started, it was going to be a digital interface display for my Innovate wideband (no analog signal loss), but displaying MegaSquirt data is just as good.
Here it is running on the MegaSquirt:
http://youtu.be/pJhWr3sL1ks

These displays are ridiculously easy to use, they use one 74hc595 (shift register) per display and passes overflow data on to the next chip, so all you need to do is send out one byte per digit... In this case, 16 bytes.
I was a little worried about overtaxing the MS processor, I know these microcontrollers can be lacking in available clock cycles, but it seems to be taking it ok (even with bit-banging the SPI data).

Well... The engine is done, or is it that I'm done with it? Either way.

It's been having a little blow-by issues on #1, manageable, it wasn't burning oil... Then one day while cruising, big cloud of black smoke, super rich... Now it smokes and burns oil.
I thought an injector was messed up and #1 was getting worse, but apparently not...

This was nearly 3 weeks ago.

Apparently, that cloud wasn't an injector, nor was it #1... It was #3.
Must have popped a ring-land, or broke a ring... Because tonight I finally got around to pulling spark plugs, #1 was a touch lean, #2 looked good, #4 looked good, #3 completely soaked in oil, though seems not enough to completely foul out the plug because it was still able to light off somehow (thus the burning oil and rich AFR).

Not that it matters if it's #1 or #3 that's jacked up, it's done, I've parked it and now have a nice cheap 2002 Audi A6 Quattro 4.2 as a daily driver.

Know something I don't? :lol:
That's not a bad deal, I would have to source a trans or bell housing for it... In the end it'll still have the same crummy FS5W71C transmission behind it...

I think if I ever had to replace that trans again, I'll have to go with a FS5R30A from a TT 300ZX... The old W71C's just don't hold enough power.

Slushbox comes with it, give your clutch foot a break for a while! Might not be as fun as rowing, but that didn't take away anything from my buddy's R33 Skyline back in Italy.

Eh, the only "auto" I'd ever like is a double clutch (DSG), but even those are more manual than slushbox.
Besides, the Audi's got an auto (which will probably be swapped before too long).

It also means I'd need a custom prop shaft (of course I would need one with the R30A trans too), but those auto boxes aren't known for their power handling capabilities either.

You waiting for taxes or what? Don't tell me you've gone to the kraut side now... Not that there's anything wrong with that!

No one seems to want to buy it... So maybe I'll get around to modifying the S13 rear multilink suspension to it, and maybe yank the engine and strip it down.

I donno what to do with it... I know I'm getting tired of moving it in and out of the garage when I need to do work on the Audi or anything else! :lol:

Hard to believe it's been 5 years since I sold the car... Anyway, since Photobucket sucks the big one, I had pulled all my pictures/videos and deleted my account.
I've gone through the thread and fixed my posts that had broken Photobucket links, but apparently the forum during one of the many software updates must have removed some image embeds... So there are still some spots where there should be pictures.
I didn't take the time to sift through my pics to figure out what went there, but if someone wants a specific picture, I can try to find the one that goes there.

It was a sad trip down memory lane, especially those last few before I parked it... Just didn't have the income to keep dumping into it, that's life though!

Yeah man. I know what you mean. This is the last year for me. If I can’t get mine on the road this year I’m done.
